Description
Field of the Invention
[0002] This invention relates to personal body shields and more particularly to a protective shield for reducing rubbing of a vehicle restraint system belt upon a sensitive or physically impaired body area.
Background of the Invention
[0003] The safety benefits of a vehicle restraint system belt are well known and undisputed. Most states require drivers and occupants to wear shoulder and lap belts. Although there has been a substantial increase in belt usage, many physically disadvantaged drivers and passengers refuse or are unable to wear belts because of pain and discomfort. Tender body areas are irritated by the restraint system belt rubbing on implants, such as heart pacers, chemotherapy ports, and defibrillators or sensitive body areas, including mastectomy scars, thoracotomy scars, appendectomy scars, laparotomy scars, chest injuries, skin rashes, and pregnancies. Areas with bandages and medications have also discouraged drivers and passengers from using restraint system belts.
Summary of the Invention
[0004] The present invention completely overcomes the objections of physically disadvantaged persons to wearing restraint system belts. The invention resides in the ability of applicants' protective shield to eliminate or reduce rubbing of a restraint system belt on a sensitive or physically impaired body area by spacing the belt away from the sensitive or physically impaired body area. One further benefit is that the invention does not require changes to current restraint systems. Another benefit is that it is easy to use. A still further benefit is that it is applicable to both seat and shoulder belts. A still further benefit is that it has little, if any, effect on restraint system effectiveness.
[0005] In a first embodiment of the invention, a resilient annular pad is joined to a thin flat bracket. The thin bracket has a pair of slotted apertures for attaching the protective shield to a lap or shoulder belt. In the installed condition, the lap or shoulder belt rests on the top of the bracket. The location of the protective shield on the belt is adjustable to position the shield opposite the sensitive or physically impaired body area.
[0006] In a second embodiment of the invention, a second pair of slots are provided in a shield of similar construction to the first embodiment for rotating the shield 90 degrees on the belt.
[0007] In a third embodiment of the invention, a thin unitary single piece shield has an elongated center portion for supporting a portion of a belt and slotted downward extending opposite end portions for retaining the shield on the belt and spacing the belt away from a sensitive or physically impaired body area.
[0008] In a fourth embodiment of the invention, the length of the elongated center portion of the second embodiment is selectively adjustable.
[0009] In a fifth embodiment of the invention, a sensitive or impaired body area is shielded by a pair of pads which space a portion of the belt away from the concerned body area.
[0010] In a sixth embodiment of the invention, the spaced apart pads of the fourth embodiment are connected by a thin narrow resilient band to space an extended portion of a restraint system belt away from a large sensitive or physically impaired body area such as the abdominal region of a pregnant woman.
[0011] Further objects, benefits and features of the invention will become apparent from the ensuing detailed description and drawings which illustrate and describe the invention. The best mode which is contemplated in practicing the invention together with the manner of using the invention are disclosed and the property in which exclusive rights are claimed is set forth in each of a series of numbered claims at the conclusion of the detailed description:

Detailed Description of a Preferred Embodiment
[0032] Refer now to the drawings wherein like numerals designate like and corresponding parts throughout the several views. In FIG. 1, a person 21 is shown wearing a shoulder belt 22 with a protective shield 23 according to our invention. The protective shield 23, as shown in enlarged form in FIGS. 2 and 3, is comprised of a thin flat bracket 24 and an annular cellular foam pad 25 between the shoulder belt 22 and the bracket 24. The annular pad 25 is attached to the bracket 24. The thin bracket 24 has a pair of opposite outward extending tabs 26, each with a slotted aperture 27 for attaching and positioning the shield 23 on the shoulder belt 22. The outer portions of the tabs 26 have cut portions 28 to install the shield 23 on the belt 22. Apertures 29 extend through the bracket 24 for ventilating the sensitive or physically impaired body area.
[0033] When the shield 23 is properly positioned, a portion of the belt 22 is spaced away from the sensitive or impaired body area with the pad's open center portion opposite the sensitive or physically impaired body area. Thus, rubbing or contact of the belt 22 with the concerned body area is reduced or eliminated. It will be appreciated that the pad 25 need not be resilient nor cellular since air filled or rigid pads can serve a similar purpose.
[0034] In FIG. 4 an alternate embodiment 30 is shown of similar construction to the FIGS. 1 through 3 embodiment 23, except that a second pair of slotted tabs 31 have been added at 90 degrees to the first pair 26. The second pair of slotted tabs 31 allow the shield 30 to be mounted at optional orientations on the belt 22.
[0035] Referring now to FIGS. 5 through 7, inclusive, an embodiment 32 is shown which is a thin unitary single piece shield 32 with an elongated center portion 33 for supporting a portion of the restraint system belt 22 and opposite end portions 34 with slots 35 for retaining the shield 32 on the belt 22 and spacing the belt 22 away from a sensitive or physically impaired body area.
[0036] In FIGS. 8 through 11, inclusive, an embodiment 36 is shown which is similar to the FIGS. 5 through 7 embodiment 32, except that the length of its center portion 37 is selectively adjustable by a user to cover smaller or larger sensitive or physically impaired body areas. The adjustment of the center portion 37 is achieved by dividing the center portion 37 into two parts, i.e, a channel cross-section member 38 and the other an engaging flat cross-section member 39. Rows of serrations 40 in the sides of the flat cross-section member 39 engage inward extending projections 41 of the channel cross-section member 38 to maintain a selected length of the shield 36.
[0037] In FIGS. 12 through 15, an embodiment 42 is shown wherein a sensitive or physically impaired body area is shielded by a pair of resilient cellular pads 43 which space a portion of the restraint system belt 22 away from a sensitive or physically impaired body area. Each of the pads 43 has a slot 44 for engaging the restraint system belt 22. The location of each of the pads 43 on the restraint system belt 22 is selectively adjustable to position a portion of the belt 22 away from the affected area.
[0038] In FIGS. 16 through 19, inclusive, an embodiment 45 is shown for preventing or reducing a rubbing of a three point anchored seat and shoulder belt 46 on an abdominal area 47 of a pregnant woman 48. The shield 45 for the abdominal area 47 is comprised of a pair of slotted cellular pads 49 which are interconnected with a thin narrow resilient band 50. The resilient band 50 has a stiffness which is sufficient to prevent the force of a belt retracting system from straightening the band 50 when the belt 46 is worn. A stiff pre-formed arcuate band (not shown) can be used in lieu of the resilient band 50. Each of the pads 49 has a pair of slots, one 51 for attaching the resilient band 50 to the pad 49 and another 52 for attaching the belt 46 to the pad 49.
[0039] In FIG. 17, the pads 49 and band 50 are shown with the shield 45 in a free condition without the belt 46. In FIG. 16, the pads 49 and band 50 are shown in an operative condition with the seat belt 46 worn and in phantom in an inoperative condition when the belt 46 is not in use. In the inoperative condition, the shield 45 is stored adjacent to the restraint system belt 46 which is retracted into a vehicle lock pillar 53. In the operative condition, the cellular pads 49 are preferably located on the belt 46 to concentrate belt loads on or near the woman's hips. The resilient band 50 and pads 49 space the seat belt away from the woman's abdomen.
[0040] From the foregoing, it will be understood that our invention provides a means for a physically disadvantaged person to wear restraint system belts without discomfort. Moreover, it will encourage the use of restraint system belts with resulting decreases in vehicle injuries and deaths.
[0041] Although only several embodiments of our invention have been illustrated and discussed, it is not our intention to limit our invention to these embodiments, since other embodiments can be developed from our disclosure by such changes as part substitution and changes in size, shape, and material alterations without departing from the spirit thereof.
