March 30, 1965 J. M. ROBBINS SEAT BELT ESGUTCHEON Filed March 23, 1964 .8 mo Y m m @V /M M S w E A H- Y E 20 United States Patent 3,175,862 SEAT BELT ESCUTCHESN James M. Robbins, 1651 Vinsetta Blvd, Royal Ualr, Mich. Filed Mar. 23, 1964, Ser. No. 354,016 8 Claims. (Cl. 297-385) This invention relates to a protective cover or escutcheon for safety seat belts which may be applied to the junction between the ends of the belt and various fastener elements employed with the belt.

Seat belts commonly employed in cars for safety purposes normally comprise two sections of webbing, each of which has one end fastened to the floor or frame of the car at spaced apart points. The other edges of the webbing sections carry buckle elements which are adapted to be joined together so that the belt forms a loop for restraining the forward motion of the passenger wearing the belt with respect to the seat. The ends of the two webbing sections are fixed to the floor fasteners and to at least one of the elements of the buckle by means of loops which are sewn in the belts and which surround slots in the fastener elements.

The primary purpose of the present invention is to provide an escuteheon formed of a resilient material such as a plastic, which will encompass these loops formed on belt ends so as to provide a finished appearance to the junctions as well as other advantages.

One of the advantages which such escutcheons provide, in addition to a pleasing appearance, is the elimination 'of the need to provide a relatively large sewn area at the and which additionally will provide a junction which is strong enough to absorb the forces which may be imposed on the belt, it is necessary to sew a relatively large area with a fiat intricate stitch. It is possible to provide the required strength with a very narrow dense stitch whichextends across the width of the belt such as the volutement stitch known to the sewing trade. However, such stitch does not provide an aesthetic finished appearance and, moreover, it rises a fair distance over the surface of the sewn material and thereby provides a surface which may potentially scratch or catch the clothes of a person wearing the belt. The present escutcheons completely cover the sewn area which forms the loop. of the belt and a stitch of the volutement type may therefore be employed to form the belt loop. This allows a belt to be formed from a shorter section of webbing and also saves sewing thread.

Other advantages of the present escuteheon reside in the fact that it may act as a handle to insert the tongue of the buckle mechanism into the mating section at an end of the other belt. It may also act as a stop for retractors which are commonly employed with seat belts. The present escutcheon also acts to protect the wearer from the relatively rough ends of the belts which are normally scared to prevent their unravelling. Additionally, the escutcheon provides a convenient place for a label bearing the information currently required by governmental a thorities as well as other trademark information.

A preferred embodiment of the present invention, which will subsequently be disclosed in detail, is formed of a thermo-setting plastic such as polyethylene by an appropriate process such as injection molding. It includes a flattened tubular section having an interior passageway adapted to snugly engage the belt webbing. One of the sides of this tubular section is offset in a direction per- 3,175,862 Patented Mar. 30, 1965 "ice pendicular to the thickness of the interior passage. An elongated flap extends from one side of the offset tubular section. This flap is adapted to be passed through a slot in a fastener member and then tucked into the offset portion. In use the offset portion encompasses the sewn area and the flap surrounds the outer side of the loop.

The flap preferably has a flange form on its extreme end which is adapted to catch in the offset portion beyond the end of the loop.

Other objects, advantages, and applications of the present invention will be made apparent from the following detailed description of a preferred embodiment of the present invention. The description makes reference to the accompanying drawing in which:

FIGURE 1 is a perspective view of an entire safety seat belt assembly which employs the escutoheons of the present invention at the two ends of the belt which are attaohed to floor fasteners as well as the end of the belt which is attached to the tongue of the belt buckle;

FIGURE 2 is a perspective view of the end of the belt which is looped about a fioor fastener end plate and which has an escutcheon of the present invention surrounding its end, prior to the insertion of the escutcheon flap through the end plate loop; and

FIGURE 3 is a cross-sectional view through a belt end attached to a floor fastener and protected by an escutcheon of the present invention.

Referring to the drawings the present invention may be employed in connection with a safety seat belt comprising a pair of woven webbing belt straps lit) and 12. The belts l0 and 12 must have sufiicient strength to withstand the maximum force which might be imposed by reason of the inertia of a passenger on the sudden stopping of the car. This is normally in the range of 4,0006,000 lbs. One end of each of the belts is fixed to the floor or the frame of the vehicle by means of

floor fasteners

14 and 16. The fasteners may be bolts which pass through the floor 18 of the vehicle and are fixed thereto by suitable locknuts 2b as well as any other variety of end fasteners. The belts are attached to the floor fasteners 14 and 15 by means of

flat end plates

22 and 24. The

end plates

22 and 24 each constitute a flat metal plate generally triangular in shape and having

slots

26 and 28 formed parallel to one of their sides and central holes 30 adjacent to one of their apexes. The bolt 14 passes through the hole 3% so as to retain the end plate to the floor of the vehicle.

The other end of the belt it? passes through and is fixed to a female buckle element 32. The extreme end 34 of the belt extends out of the female buckle 32 and the effective length of the entire seat belt may be adjusted by varying the point of joinder between the belt ill and the female buckle element 32.

The other ends of the belt 12 is fixed to a tongue 36 which acts as a male buckle member and is engageable with the female buckle member 32 for purposes of closing the belt. The exact configuration of the male tongue 36 is not of importance, however, it has a slot 38 adjacent to one side which is similar to the slots 26 and 23 in the

end plates

22 and 24. j

For the purposes of the present invention, the joinder between the belt ends which are attached to the tongue 36 and to the

end plates

22 and 24 are identical. In each case, the extreme end of the belt is passed through the slot (26, 23, or 38) and the belt end is then sewn across a point removed from the end as at 40 in FIGURE 2 so as to form a loop 42 in the belt. With the present invention the sewn seam 40 which finishes the loop 42 may be of a compact highly dense stitch which extends a relatively high distance beyond the surface of the belt. As has been noted, the alternative to forming such a highly dense stitch is to connect a relatively wide belt area in forming the loop. In such a case, a lower more finished stitch may be employed so as to achieve the same bond strength as is provided by the dense narrow stitch as.

Escutcheons, or protective coverings, formed in accordance with the present invention are employed at the

end plates

22 and 24 and at buckled tongue 36 to cover the loop ends to provide the advantages set forth in the preamble hereto. The escutcheons at these three points are identical and are generally indicated at St). The escutcheons are preferably formed of a flexible resilient material such as a thermo-setting plastic and they may be formed by injection molding.

As is best illustrated in FIGURE 2, the escutcheons in elude a narrow thin tubular section 52 which has a central passageway 54 through which the belt webbing may pass. The passageway 54 has dimensions such that it tightly encompasses the belt and its extreme ends are tapered as at '56 and 58 so as to provide a relatively smooth snag-free surface between the belt and the escutcheon.

One of the walls of the tubular section 52 is offset as at 60 in a direction perpendicular to the surface of the belt so as to create a generally offset section to receive the stitched section 4t) of the belt and a flap as will be detailed subsequently. The oifset section 60 is joined to the narrow tubular section 52 by an outwardly inclined wall 62. The offset section surrounds the belt webbing and provides room for the sewn seam 40 and the flap .as will be noted. The flap 64 extends from the non-offset wall adjacent the end of the ofivset section 60. The side walls of the flap 64 are tapered inwardly adjacent to its extreme end 66 in order to ease its insertion through the

slots

26, 28, and 38 of the hardware attachments to the offset portions of the escutcheon. The extreme edge has a flange 68 extending across its width in the direction of the offset portion 60. The slot 70 across the major portion of the width of the flap 64 between the tapered edges 66 aids the flexibility of the flap section and assists in accommodating the sewn seam 40 when the escutcheon is in position.

In use, the

tubular sections

52 and 60 of the escutcheon are slid over the belt before the end of the belt is passed through the slots in the hardware and sewn at 40. The end of the tab 64 is then passed through the slot in the hardware and brought back over the loop into the offset portion 60. As is shown in FIGURE 3, the sewn seam 40 and the end of the flap 64 are accommodated Within the offset portion. The flange 68 presses beyond the edge of the belt webbing so as to assist in the retention of the flap in the offset portion.

As may be seen, the escutcheon completely covers the seam 4t) and the extreme end of the belt. The escutcheon provides only smooth snag-free plastic surfaces and may be additionally embossed so as to simulate the weave of the belt or otherwise asethetically blend therewith. The stiffness of the escutcheon makes it a convenient handle for the buckle tongue 36.

The escutcheon of the present invention is therefore seen to provide a simple, low cost, and easy to apply device for protecting and enhancing the appearance of safety belt ends attached to the various parts of belt hardware.
