Abstract

A vehicle restraint system with a housing for a seat belt retractor, the housing having a rotatable escutcheon with an exit slot for the seat belt webbing. The escutcheon is preferably mounted to a bearing attached to the housing.

Claims

1. A vehicle restraint system comprising:

a) a seat belt retractor for releasably storing a seat belt webbing;

b) a seat belt webbing releasably stored in said seat belt retractor;

c) a housing through which the webbing extends;

d) an escutcheon rotatably mounted to the housing, said escutcheon having a slot through which the seat belt webbing is disposed, wherein the escutcheon includes a circular face plate with a shaft projecting axially therefrom, the shaft having a free end, and further including an opposite end in direct relationship contact with the face plate.

2. A vehicle restraint system comprising:

a) a seat belt retractor for releasably storing a seat belt webbing;

b) a seat belt webbing releasably stored in said seat belt retractor;

c) a housing through which the webbing extends;

d) an escutcheon rotatable mounted to the housing, said escutcheon having a slot through which the seat belt webbing is disposed,

wherein the housing includes a plurality of support struts connected to a bearing having an axial bore, and

an escutcheon shaft rotatably disposed within said axial bore.

3. The vehicle restraint system of claim 2 further including snap fit means for snap fit engagement of the escutcheon shaft with the bearing.

4. The vehicle restraint system of claim 3 wherein the snap fit means includes a circumferential groove disposed on the shaft in a vicinity of the free end thereof, and an annular lip portion disposed at one end of the axial bore of the bearing, the annular lip portion being received into the circumferential groove.

5. The vehicle restraint system of claim 2 wherein the housing includes a circular aperture.

6. The vehicle restraint system of claim 5 wherein the escutcheon is mounted within the circular aperture of the housing.

7. The vehicle restraint system of claim 6 wherein the escutcheon has a recessed annular flange portion having a diameter smaller than the diameter of the circular aperture of the housing.

8. The vehicle restraint system of claim 2 wherein the housing is fabricated from a material selected from the group consisting of polycarbonate, acetals, acrylic polymers, nylon, polyesters, aluminum, and steel.

9. The vehicle restraint system of claim 2 wherein the axial bore of the bearing is lined with a low friction material.

10. The vehicle restraint system of claim 9 wherein the low friction material comprises polytetrafluoroethylene.

11. The vehicle restraint system of claim 2 wherein said support struts are integrally fabricated within the housing.

12. The vehicle restraint system of claim 2 wherein the support struts are removably connected to the housing.

13. The vehicle restraint system of claim 12 wherein each of said support struts includes a plate forming a T-shaped end structure which is insertable into corresponding slots in the housing.

14. The vehicle restraint system of claim 2 wherein the escutcheon includes a circular face plate and wherein the shaft projects axially therefrom, the shaft having a free end.
