Abstract

A latch plate for use with a seat belt and seat belt buckle, the latch plate comprising: a metal load-bearing plate including a generally flat tongue engageable with a locking feature of the seat belt buckle, a first portion of the bearing plate, rearward of the tongue, having a first surface, the first surface including a lateral extending rearward edge; the bearing plate, in a second portion thereof, including an integrally formed tab having a laterally extending forward edge, the forward edge of the tab overlaying the rearward edge of the first surface, the tab being spaced a determinable distance from the first surface defining a thin channel or opening therebetween through which the seat belt is received, the distance being sufficiently narrow to lessen the likelihood of the seat belt becoming twisted in the channel.

Claims

1. A latch plate (50) for use with a seat belt and seat belt buckle, the latch plate comprising:

a metal load-bearing plate (52) including a tongue engageable with a locking feature (54) of the seat belt buckle,

a first portion of the load-bearing plate, rearward of the tongue (58), having a first surface, the first surface (70) including a lateral extending rearward edge (72);

the load-bearing plate, in a second portion thereof, including an integrally formed tab (62) having a laterally extending forward edge (74), the forward edge of the tab overlaying the rearward edge (72) of the first surface, the tab being spaced a determinable distance from the first surface defining a thin channel or opening (80) therebetween through which the seat belt is received, the distance being sufficiently narrow to lessen the likelihood of the seat belt becoming twisted in the channel.

2. The latch plate as defined in claim 1 wherein the first surface is flat.

3. The latch plate as defined in claim 1 wherein one of the first surface and the tab is generally flat and includes a plurality of upraised projections thereon.

4. The latch plate as defined in claim 3 wherein the projections are one of hemispherical and oval.

5. The latch plate as defined in claim 1 wherein the tab is generally parallel to the first surface.

6. The latch plate as defined in claim 1 wherein the at least facing portions of the tab and the first surface, in the vicinity of the channel, are covered by a low friction, elastomeric coating to permit a latch to easily slide upon the seat belt.

7. The latch plate as defined in claim 5 wherein the coating, within the channel, includes a plurality of projections projecting into the channel.

8. The latch plate as defined in claim 7 wherein adjacent projections on the flat surface and on the tab alternate.

9. The latch plate as defined in claim 1 wherein the first surface of the load-bearing plate and the tongue lie in the same plane.

10. The latch plate as defined in claim 1 wherein a third portion of the bearing plate, rearward of the second portion, is elevated relative to the tongue.

11. The latch plate as defined in claim 1 wherein the load-bearing plate includes a thin U-shaped slot immediately rearward of the first surface, the U-shaped slot forming the tab, the rearward edge of the first surface and the forward edge of the tab.

12. The latch plate as defined in claim 11 wherein the tab is initially bent at an angle away from the plane of the tongue, and wherein the bearing plate is bent in the vicinity of the slot to position the forward edge of the tab to overlay the rearward edge of the first surface.

13. A latch plate (50) for use with a seat belt and seat belt buckle, the latch plate comprising:

a load-bearing plate (52) including a tongue engageable with a locking feature (54) of the seat belt buckle,

a first portion of the load-bearing plate, rearward of the tongue (58), having a first surface, the first surface (70) including a lateral extending rearward edge (72);

the load-bearing plate, in a second portion thereof, including an integrally formed tab (62) having a laterally extending forward edge (74), the forward edge of the tab being spaced a determinable distance from the first surface defining a thin channel or opening (80) therebetween through which the seat belt is received, the distance being sufficiently narrow to lessen the likelihood of the seat belt becoming twisted in the channel.

14. A latch plate (50) for use with a seat belt and seat belt buckle, the latch plate comprising:

a metal load-bearing plate (52) including a tongue engageable with a locking feature (54) of the seat belt buckle,

a first portion of the load-bearing plate, rearward of the tongue (58), having a first surface, the first surface (70) including a lateral extending first edge (72);

the load-bearing plate, in a second portion thereof, including an integrally formed tab (62) having a laterally extending second edge (74), the second edge overlaying the first edge (72) of the first surface, the tab being spaced a determinable distance from the first surface defining a thin channel or opening (80) therebetween through which the seat belt is received, the distance being sufficiently narrow to lessen the likelihood of the seat belt becoming twisted in the channel.
