Description
Background of the Invention
1. Field of the Invention
The present invention relates to a child passenger seat for a vehicle which is capable of restraining the body of a child passenger seated thereon in an emergency situation of the vehicle.
2. Description of the Related Art
Child passenger seats are employed for restraining the bodies of child passengers when an emergency situation of the vehicle occurs.
A typical conventional child passenger seat is arranged such that the main structure of the seat is mounted on a seat of a vehicle, and a restraining means provided on the main structure, such as a seatbelt means, is fastened around the body of a child passenger.
The main structure of this type of child passenger seat is preferably provided with a cushioning pad for the purpose of absorbing the impact applied when the body of a child passenger hits the seat structure. The pad is usually attached to the seat structure by means of bonding, and this involves a risk of bonding failure which would cause the pad to separate from the seat structure and also involves difficulties in replacing or washing the pad when stained to a substantial extent.
Summary of the Invention
In view of the above-mentioned circumstances, it is a primary object of the present invention to provide a child passenger seat for a vehicle so designed that the cushioning pad thereof is readily replaced or washed.
To this end, the present invention provides a child passenger seat for a vehicle in which a cover of the seat is provided with a double-sheet portion for accommodating a cushioning pad.
By virtue of this arrangement, the handling of the cushioning pad is facilitated, since the pad is mounted on the cover and need not be attached directly to the shell by bonding or other similar means.
The shell is preferably provided with a pad accommodating recess, whereby it is possible to prevent the seating surface for a child passenger from becoming uneven to a substantial degree.

Description of the Preferred Embodiment
One embodiment of the child passenger seat according to the present invention will be described hereinunder.
FIG. 1 is an exploded perspective view of the child passenger seat which includes a shell 10 and a cover 12 which is fitted over it.
It is preferable that the shell 10 is integrally molded from a material which is able to bear a predetermined load, such as a synthetic resin. The child passenger seat is mounted on a seat of a vehicle in such a manner that the front end of the seat which faces in the direction of the arrow A is directed toward the front end of the vehicle.
The shell 10 includes a seat panel 10A and a backrest panel 10B which extends upwardly from the rear end of the seat panel 10A. A pair of side panels 10C are connected to the right and left ends of the seat and backrest panels 10A and 10B. The seat panel 10A is provided with a through-hole 14 for passing a crotch belt (not shown), while the backrest panel 10B is provided with through-holes 16 for passing shoulder belts (not shown). The crotch and shoulder belts which are passed through the through-holes 14 and 16 are retained by the shell 10 at the rear sides of the seat and backrest panels 10A and 10B, respectively.
Notches 18 are respectively provided in the end faces 10D of the side panels 10C which face the front end of the vehicle so that an adult passenger restraining means provided on a seat of the vehicle are passed through the notches 18, and the shell 10 is thereby secured to the seat of the vehicle.
As also shown in FIG. 4, recesses 20 are formed in the upper end portions of the seating surfaces defined by the backrest and side panels 10B, 10C of the shell 10, the recesses 20 having a depth D. A cushioning pad 22 is fitted in and bonded to the recess 20 formed in the backrest panel 10B.
The cover 12 is constituted by a fabric structure or the like which includes a seat member 12A, a backrest member 12B which is integrally connected to the end of the seat member 12A on the side thereof which is closer to the rear end of the vehicle, and a pair of side sheet members 12C which are respectively sewn to the lateral edges of the seat and backrest members 12A and 12B. When the cover 12 is fitted over the shell 10, the seat, backrest and side members 12A, 12B and 12C are respectively brought into contact with the surfaces of the seat, backrest and side panels 10A, 10B and 10C, thus defining a seating surface for a child passenger.
The forward end portions (as viewed in the longitudinal direction of the vehicle) of the side members 12C are sewn to the forward end portions of outer members 12D, respectively. In consequence, pouch-like portions 23 are respectively defined between the side members 12C and the outer members 12D, the rear sides of the pouch-like portions 23 being open, so that the pouch-like portions 23 can be respectively fitted over the side panels 10C of the shell 10.
A rear member 12E is sewn to the upper end portion of the seat member 12A. The right and left end portions (as viewed longitudinally of the vehicle) of the rear member 12E are respectively sewn to the rear ends of the upper portions of the side members 12C. Consequently, a pouch-like portion 25 is defined between the rear member 12E and the backrest member 12B, the lower side of the pouch-like portion 25 being open, and the portion 25 being communicated with the pouch-like portions 23 defined between the side members 12C and the outer members 12D.
Thus, the cover 12 is mounted on the shell 10 in such a manner that the pouch-like portions 23 and 25 are respectively fitted over the upper portions of the side and backrest panels 10C and 10B of the shell 10, whereby it is possible for the cover 12 to be readily fitted over the shell 10.
As shown in FIG. 3 in detail, a pocket-defining member 26 is provided between each of the side member 12C and the corresponding outer member 12D. The configuration of the pocket-defining member 26 is made conformable to that of the upper end portion of the side member 12C. The upper and forward end portions of the pocket-defining member 26 is sewn together with the side member 12C and the outer member 12D when these members are sewn together. The lower end portion of the pocket-defining member 26 is sewn to the side member 12C. Thus, the pocket-defining member 26 defines a pocket the rearward side of which is open and which can accommodate a cushioning pad 28. In consequence, the pad 28, together with the pocket-defining member 26, protrudes from the surface of the side member 12C and is accommodated within the recess 20 formed in the inner side of the side panel 10C when the cover 12 is fitted over the shell 10, as shown in FIG. 6.
It is to be noted that the seat and backrest members 12A, 12B of the cover 12 are respectively provided with through-holes 30, 32 which respectively correspond to the through-holes 14, 16 provided in the shell 10 so that the through-holes 30, 32 can pass the crotch and shoulder belts, respectively.
In the child passenger seat in accordance with this embodiment, arranged as detailed above, the pad 22 is attached to the recess 20 in the backrest panel 10B of the shell 10 in advance by means, for example, of bonding. The thickness of the pad 22 is set such as to be substantially equal to the depth of the recess 20.
Similarly, the pads 28 are respectively inserted into the pockets defined by the pocket-defining members 26 of the cover 12. The thickness of these pads 28 is set such as to be similar to that of the pad 22.
Then, the cover 12 is mounted on the shell 10, whereby the former is fitted over the latter, and the pads 28 are respectively accomnodated in the recesses 20 of the side panels 10C.
Since the pads 22 and 28 are accommodated in the respective recesses 20, there is no risk of the upper end portions of the backrest and side panels 10B and 10C greatly protruding toward the child passenger seated on the seat, so that he feels no unpleasantness and can enjoy a comfortable ride.
This child passenger seat is mounted on a seat of a vehicle and secured to the seat by utilizing the notches 18, and a child passenger is thereby allowed to seat himself on the seat member 12A. After the child passenger has been seated, the crotch and shoulder belts projecting from the seating surface are passed over the front side of the body of the child passenger and engaged with each other, thereby allowing his body to be fastened by these restraining means. Thus, when an emergency situation of the vehicle occurs, the body of the child passenger is restrained by the restraining means.
The pad 22 in the described embodiment may be accommodated in a pocket which is formed on the cover 12 beforehand in a manner similar to that of the pads 28.
Since the pads 28 are accommodated in the pockets, it is possible for the pads 28 to be readily replaced or washed by taking them out of the pockets when necessary.
