((11. 297-385) This is a continuation-in-part application of the applications, Serial No. 253,819, filed January 25, 1963, now abandoned and Serial No. 392,258, filed August 26, 1964.

This invention relates to vehicle seat belts and in particular to a protective plate for placing between the abdomen and the seat belt.

When the wearer of a seat belt is thrown forward against the belt, the belt and the metal buckle are pulled into the abdomen of the wearer and may cause injury. Moreover, the seat belt buckle usually made of metal is frequently uncomfortable especially if it is held tight against the abdomen. Also, the belt and the buckle tend to wrinkle the wearers clothing.

Thus it is one of the principal objects of this invention to provide a protective plate which may be positioned between the seat belt and the wearers abdomen to protect the wearer against injury caused by the seat belt being pulled tight against the abdomen.

It is'a still further object of this invention to provide a protective plate which may be positioned between the seat belt and buckle and the wearers abdomen to prevent the wrinkling of the wearers clothing.

A still further object of this invention is to provide a protective abdominal plate for use with vehicle safety belts which is shaped to conform to the wearers adbomen and also to be held in position above and between the wearers legs.

A still further object of this invention is to provide a protective abdominal plate for use with vehicle safety belts which has a top flange so shaped to prevent injury to the wearer upon being thrown forwardly over the plate.

A still further object of this invention is to provide a protective abdominal plate for use with vehicle safety belts which is so shaped to maintain the seat belt on the protective plate at all times.

A related object of this invention is to provide a protective-abdominal plate for use with vehicle safety belts which has means for-maintaining ventilation through the protective plate.

Another related object of this invention is to provide a protective abdominal plate for use with vehicle safety belts which is flexible and will thereby bend under stress. It is also desired that the protective abdominal plate be of a material which is resilient and will return to its normal shape'upon the removal of the stress forces.

A further object of this invention is to provide a protective abdominal plate for use with vehicle safety belts which has a means thereon for detachably securing the seat belt thereto.

A further object of this invention is to provide a protective abdominal plate for use 'with vehicle; safety belts which may be detachablysecured to. the vehicle safety belt so thatthe protectiveabdominalplate will alwaysbe witliirilctmvenient reach of the wearer.

slightly ab'oveithe top of the passenger withthe' padding A further object of this invention is to provide a protective abdominal plate for use with vehicle safety belts which is simple in design, economical to manufacture and refined in appearance.

These and other objects will be apparent to those skilled in the art.

This invention consists in the construction, arrangements, and combination of the various parts of the device, whereby the objects contemplated are attained as hereinafter more fully set forth, specifically pointed out in the claims, and illustrated in the accompanying drawings, in which:

The numeral 10 generally designates a lightweight plate f Plate 10 assumes padding 18 is secured to the rearward surface of sheet 10 by any convenient means such as by rivets 20 which ex- I tend through some of the apertures 16.

A conventional seat belt 21 is comprised of belt por--' ltions 22 and 24 which each have their respective rearward ends anchored to the vehicle frame by brackets 26. Belt 1 portion 22 has a conventional friction-type buckle 28- secured to its forward end. Buckle 28 is adapted to receive and hold the forward end of belt portion 24;

Two U-shaped hooks 30 are detachably mounted on plate 10. Each hook 30 is comprised of a vertically dis- I posed loop 32 which has horizontal legs 34 extending towards the front of the plate 10. Legs 34 are bent upwardly at the face of the plate to form vertical portion 36. The upper ends of the vertical portions 36 are bent rearwardly to form horizontal portions 38 which detachably extend through pairs of apertures 16 in plate 10. Hook portions 30 on the rearward ends of the horizontal portions 38 extend upwardly to engage the rearward surface of plate 10 to present the downward or forward movement of the hooks with respect to the plate.

Theanormaloperationof the device seen in FIQS l- S isasfollowsajjxx. N I The plate. 10 is'.p'lace'd with its bottom edge on or 18 against the passengers abdomen. The hooks 30 are tilted upwardly and rearwardly to permit hook portions 40 and the horizontal portions 38 to be inserted into plate through pairs of apertures 16. The padding 18 is slightly deflected by the hook portions 40. The hooks 30 are then tilted back to the position shown in FIG. 5. The books 30 should be placed substantially as shown in FIG. 2 and at a height most comfortable to the passenger, but preferably below the center of plate 10. An arcuate wedge 60 which is triangular in cross-section and which may be comprised of rubber or the like, is placed against the forward surface of the plate and the belt is tightened against it. The wide edge of wedge 60 is positioned uppermost, as shown in FIG. 3. The belt portions 22 and 24 normally extend rearwardly and downwardly from plate 10 as also shown in FIG. 3.

The plate 10 and padding 18 will serve to distribute the force of belt 21 if the passenger is thrown forwardly against the belt and this serves to prevent the belt from damaging the passengers internal organs. The forwardly curved edges of the plate 10 also serve to protect the passenger from the edges of the plate. By adjusting the position of hooks 30, the plate 10 can be adapted for use by persons of different size and stature. The wedge 60 causes the tension on belt 21 to hold the weight of the plate upwardly off the lap of the passenger. Aperture 16 in plate 10 and the porous and fibrous padding 18 permit the unit to breathe so that the unit will not be uncomfortable to use in warm weather.

With respect to the device seen in FIGS. 69, the numeral 64 generally designates the protective abdominal plate. Protective abdominal plate 64 is adapted to be positioned between a persons abdomen and the seat belt buckle 66 on a seat belt 68. The seat belt 60 is secured at each of its ends 70 and 72 (not shown) to the frame 74 of a vehicle. The seat belt 68 extends from behind a vehicle seat 76 across the wearers abdomen.

The protective abdominal plate 64 is shown to be channel-shaped and having a top flange 78 and a bottom flange 80 interconnected by base portion 82. The entire plate 64 is curved or concave 'at 84 to conform to the shape of the wearers abdomen.

The top and bottom flanges 78 and 80 flare outwardly along their lengths relative to the base 82. The top flange 78 is positioned in a substantially fl-at plane along its length while the bottom flange 80 has an end portion 86 at each end thereof which is concave upwardly in shape and extends longitudinally inwardly and downward- 1y Where the two end portions are interconnected by a third portion 88 which is convexed downwardly. The convex portion 88 is placed intermediate the end portions 86 and projects along the contour of the wearers body over and between the wearers legs. Similarly, the end portions 86 are shaped to conform to the inner and upper surfaces of the wearers legs. It is seen that by this shape of the bottom flange 80 that the plate 64 is held securely in a desired position of use.

End edges 104 and 106 of the base portion 82 taper outwardly and downwardly from the top flange 78 to the bottom flange 80 and thereby makes the bottom flange 80 longer than the top flange 78. By this construction, the necessary channel length is provided for the seat belt 68 to maintain it within a channel-shaped plate 64 particularly at its ends. To provide for ventilation through the protective plate 64, a plurality of holes 92 are formed in the base 82. As best seen in FIG. 8, base 82 is provided with a pair of vertically disposed openings 84 and 96 adjacent one of its ends and vertically disposed openings 98 and 100 at its opposite end. Each of the pair of holes just described are adapted to have strap memher 102 extending therethrough as seen in the drawings. Strap 102 has conventional fasteners at its free ends. Protective plate 64 may be detachably secured to belt 68 as seen in the drawings so that the protective plate 64 will not become detached from the seat belt. This of the protective plate 64.

feature assures that the protective plate 64 will always be conveniently located and it will not be necessary for a person to grope around in an attempt to locate the protective plate. The vertically disposed openings at each end of base portion 82 permit the protective plate 64 to be detachably secured to the particular end of the seat belt which has the buckle 66 secured thereto.

The material used in fabricating the protective plate 64 should be flexible and preferably resilient. A plastic material has been found to perform quite satisfactorily. By the material being flexible and resilient, it will not break upon impact during use or storage.

It is obvious that upon the wearer bending forward as in the case of an accident, his abdomen will be protected by the protective plate 64 since the stress forces on the belt 68 will be spread over the substantial area It is also to be noted that the top and bottom flanges 78 and are rounded at their connection to the base 32 and therefore provide a smooth surface for bearing engagement with the wearers body.

Some changes may be made in the construction and arrangement of my protective abdominal plate for use with vehicle safety belts without departing from the real spirit and purpose of my invention, and it is my intention to cover by my claims, any modified forms of structure or use of mechanical equivalents which may be reasonably included within their scope.
