Description
Background of the Invention
[0002] This invention relates generally to an assembly for mounting a seat within a vehicle. More particularly, this invention relates to a locking mechanism that provides a releasable mount for a vehicle seat.
[0003] Seat track arrangements for mounting seats within vehicles are generally well known. The seat track assemblies provide for a vehicle seat to be adjusted in forward and rearward direction. To provide the adjustment, a first seat track is typically movable relative to a second seat track. The second seat track is a stationary track that is securely fastened to the vehicle floor.
[0004] It is common to mount the seat track arrangements directly to the vehicle floor by threaded fasteners such as nuts and bolts. The bolts are commonly mounted at each end of the seat tracks to extend through the seat track and the vehicle floor where it is threaded into the nut. This provides a secure mounting arrangement that assures that the seat track assembly and thus the vehicle seat are securely fastened to the vehicle.
[0005] Although the mounting of the seat track with threaded fasteners provides a secure attachment of the seat to the vehicle, it is rather time consuming to attach each fastener in an assembly environment. Further, access to the fasteners may be limited and particular assembly operations must be sequenced to assure that access to the fasteners is readily available.
[0006] Another matter of general concern with the mounting of the seat track is the emergency removal after an accident, or later maintenance that requires removal of the seat. The seat is typically originally installed prior to installation of the instrument panel and other interior components. This allows for easy access to the fasteners. However, during a later repair that requires removal of the seat, it is relatively difficult to gain access to the fasteners.
[0007] Accordingly, it is desirable to provide a seat mounting assembly that provides effective retention of the seat to the vehicle, yet allows improved attachment and removal of the seat.
Summary of the Invention
[0008] One embodiment of the present invention provides a seat mount that is preferably attached to a stationary seat track. The seat mount includes a support foot having a rotatable mounting pin that is preferably of an L-shape. A stop is fixedly mounted to the pin to retain a biasing member such as a spring between the stop and the support foot.
[0009] In use, the support foot is located on the vehicle floor member and the pin is moved downward through a slot in the vehicle floor member. While the pin is being pressed in the downward direction against the force of the biasing member, the pin is rotated within the support foot. The pin is then released such that the biasing member moves the pin upward into a receipt member. The support foot and the seat are thereby removably attached to the vehicle floor member.
[0010] Another embodiment of the seat mount includes a pin having an engagement surface. The pin is passable through the vehicle floor member an into a substantially cup-shaped receipt member. To retain the pin in the receipt member, a spring biased locking member engages an engagement surface on the pin.
[0011] In use, the locking member is retracted against the force of the biasing member by a removable tool or the like. The pin can then be installed or removed from the receipt member without the necessity of threaded fasteners.
[0012] The receipt member is preferably mounted such that the receipt member can move or “float” relative to the vehicle floor member prior to receiving the pin. By allowing the receipt member to “float” relative to the vehicle floor member during receipt of the pin, various tolerance variations between the seat and the vehicle floor member are accommodated.

Detailed Description of the Preferred Embodiment
[0024] FIG. 1 diagrammatically illustrates a vehicle seat assembly 20. The seat assembly includes a seat base portion 22 that is mounted within the vehicle on a track assembly 24 attached to a vehicle floor member 26. The track assembly 24 includes tracks on an inboard side 28 and an outboard side 29. The terms inboard and outboard used in this specification are in reference to a driver's position for clarity and illustration purposes only and cannot be considered limiting.
[0025] The track assembly 24 include a stationary first track 30 attached to the vehicle floor member 26 and a movable second track 32 attached to the seat base portion 22. The movable second track 32 engages the first stationary track 30 so that the movable second track 32 can be moved in a forward or rearward direction relative to the first track 30.
[0026] A seat mount 34 attaches the track assembly 24 to the vehicle floor member 26. The seat mount 34 is preferably located near each corner of the track assembly 24. As will be further described below, the seat mount 34 includes a mounting pin 38 that allows the vehicle seat 20 to be removably installed to the vehicle floor member 26 without the necessity of a threaded fastener.
[0027] FIG. 1A illustrates a seat mount 34 having a support foot 36 as a component separate from the mounting assembly 24. The seat mount 34 is attached to the stationary first track 30 and supports the mounting pin 38 to mount the seat 20 to the vehicle floor member 26. However, as shown in FIG. 1B, depending on the orientation of the first track 30 and second track 32, the stationary first track 30 itself can be the seat mount 34. The first track 30 includes the mounting pin 38 and the first track 30 is supported directly on the vehicle floor member 26.
[0028] FIG. 2 further illustrates the seat mount 34 attached to the vehicle floor member 26. The support foot 36 contains a rotatable mounting pin 38 that is preferably of an L-shape. A stop 40 is fixedly mounted to the pin 38 to retain a biasing member 42 such as a spring between the stop 40 and the support foot 36. The biasing member 42 provides an upward force on the pin 38 relative to the support foot 36. The force of the biasing member 42 must therefore be overcome to move the pin 38 in a downward direction.
[0029] As will be described in more detail below, the support foot 36 is located on the vehicle floor member 26 is located on the vehicle floor member 26 and the pin is moved manually downward through a slot 44. While the pin 38 is being pressed in the downward direction against the biasing member 42, the pin 38 is rotated within the support foot 36. The pin 38 is then released such that the biasing member 42 moves the pin 38 upward in the opposite direction along arrow A and into receipt member 46. The support foot 36 and thus the seat mount 34 is securely attached to the vehicle floor member 26.
[0030] FIG. 3 illustrates a front view of the support foot 36 located on the vehicle floor member 26. The pin 38 is shown in phantom at 38A after being passed through the slot 44 (FIG. 2) while being pressed in the downward direction along arrow A against the biasing member 42. After passing through the slot 44 the pin 38 is rotated in the direction of arrow B into alignment with the receipt member 46. The pin 38 is then released such that the biasing member 48 moves the pin 38 upward in the opposite direction along arrow A and into the receipt member 46.
[0031] FIG. 4 illustrates a side view of the support foot 36 located on the vehicle floor member 26. The pin 38 is again shown in phantom at 38A after being passed through the slot 44 while being pressed in the downward direction along arrow A against the force of biasing member 42. After passing through the slot 44 the pin 38 is rotated in the direction of arrow B into alignment with the receipt member 46
[0032] As shown in FIG. 4, receipt member 46 is preferably a channel located along the underside of the vehicle floor member 26. Although a channel is disclosed, one skilled in the art will understand that other receipt members 46 can be used. It should be realized that the receipt member 46 can be integral to the vehicle floor member 26. Further, the vehicle floor member 26 can be integral to a vehicle frame, or a bracket or the like attached thereto. Accordingly, by providing a receipt member 26 to receive pin 38, the vehicle seat 20 (FIG. 1) is removably installed.
[0033] FIG. 5 illustrates another embodiment of the seat mount 34′ attached to the vehicle floor member 26. The seat mount 34′ again includes a support foot 36′. However, the support foot 36′ can similarly be the stationary first track 30 as described above.
[0034] The seat mount 34′ generally includes a pin 50 having an engagement surface 52. The pin 50 is passable through the vehicle floor member 26 an into a receipt member 54. A locking member 56 is preferably biased by a biasing member 58 such that the locking member 56 engages the engagement surface 52 such as a groove in the pin 50.
[0035] The receipt member 54 is preferably a substantially cup-shaped member mounted adjacent the vehicle floor member 26. The receipt member 54 can be integral to the vehicle floor member 26. However, in the disclosed embodiment of FIG. 5, the receipt member 54 is preferably mounted such that the receipt member 54 can move or “float” relative to the vehicle floor member 26 prior to receiving the pin 50.
[0036] The receipt member 54 includes a flange 55 that fits within corresponding tabs 57 in the vehicle floor member 26. The tabs 57 preferably provide a clearance space 59 between the flange 55. The receipt member is thereby allowed to move or “float” within the confines of the clearance space 59.
[0037] An enlarged opening 63 of a greater diameter than the pin 50 is provided in the vehicle floor member 26. The pin 58 is thus received through an opening 63 that is greater than the pin 50 diameter. Accordingly, by allowing the receipt member 54 to “float” relative to the vehicle floor member 26 during receipt of the pin 50, various tolerance variations between the seat 20 (FIG. 1) and the vehicle floor member 26 are accommodated.
[0038] To retain the pin 50 in the receipt member 54, the locking member 56 engages the engagement surface 52. The locking member 56 is preferably located below and substantially parallel to the vehicle floor member 26.
[0039] In use, the locking member 56 is retracted against the force of the biasing member 58 by a removable tool 60 or the like. The removable tool 60 fits through an access opening 61 in the vehicle floor member 26 and preferably engages the locking member 56. The tool 60 s pivoted in the direction of arrow C and the locking member 56 is retracted against the biasing member 58. The pin 50 can then be installed or removed from the receipt member 54. Although a removable tool 60 is disclosed, one skilled in the art will understand that an integral latch assembly can be used to operate the locking member 56.
[0040] FIG. 6 illustrate a sectional view taken along the line X—X in FIG. 5. The locking member 56 includes a substantially C-shaped engagement surface 58. The C-shaped engagement surface 58 enters the corresponding engagement surface 52 or groove of the pin 50 to securely retain the pin 50 in the receipt member 54. The locking member preferably provides a slot 62 that receives the removable tool 60 (FIG. 5).
[0041] FIG. 7 illustrates another embodiment of the locking member 56′ having substantially U-shaped engagement surface 58′. The U-shaped engagement surface 58′ similarly enters the corresponding engagement surface 52 or groove of the pin 50 to securely retain the pin 50 in the receipt member 54. A slot 62′ again receives the removable tool 60 (FIG. 5) to retract the locking member 56′.
[0042] FIG. 8 illustrates yet another embodiment of the locking member 56″. The engagement surface 58″, however, is a male fitting which engages a female engagement surface 52′ extending through the pin 50′ to securely retain the pin 50 in the receipt member 54. A slot 62″ receives the removable tool 60 (FIG. 5) to retract the locking member 56″.
