Abstract

The invention provides a shoulder belt height adjuster assembly and a method of adjusting the same. The assembly includes a guide rail, a slide, and a biasing member. The guide rail includes a plurality of fixed rail teeth disposed along at least one longitudinal portion. The slide includes an aperture formed therein for slidably receiving the guide rail along the longitudinal portion. The slide further includes a plurality of fixed slide teeth disposed on an interior slide surface. The biasing member is operably attached to the slide aperture for selectively engaging at least one of the fixed slide teeth into at least one of the fixed rail teeth. The engagement prevents slidable movement of the slide relative to the guide rail in a downward direction. The method includes selectively preventing sliding movement of a slide relative to a guide rail, sliding the slide in an upward direction by applying an upward force, and sliding the slide in a downward direction by applying a pressing force and a downward force.

Claims

1. A shoulder belt height adjuster assembly for a motor vehicle, the assembly comprising:

a guide rail including a plurality of fixed rail teeth disposed along at least one longitudinal portion, wherein the guide rail comprises a single piece that is substantially U-shaped;

a slide including an aperture formed therein for slidably receiving the guide rail along the longitudinal portion, the slide including a plurality of fixed slide teeth disposed on an interior slide surface; and

a biasing member operably attached to the slide aperture for selectively engaging at least one of the fixed slide teeth into at least one of the fixed rail teeth;

wherein said engagement prevents slidable movement of the slide relative to the guide rail in a downward direction.

2. The assembly of claim 1 wherein the guide rail comprises a cross-sectional shape selected from a group consisting of a square, a rectangle, an oval, and a circle.

3. The assembly of claim 1 wherein the biasing member comprises at least one bend formation.

4. The assembly of claim 1 wherein the biasing member is positioned substantially within the slide aperture.

5. The assembly of claim 1 wherein the fixed rail teeth comprise a saw-tooth configuration.

6. The assembly of claim 1 further comprising:

at least one mount for operably attaching the assembly to the motor vehicle; and

a D-ring operably attached to the slide and to a shoulder belt.

7. The assembly of claim 6 wherein the mount comprises a bolt mount.

8. The assembly of claim 6 wherein the mount comprises a hook mount.

9. The assembly of claim 6 wherein the mount comprises a pocket mount.

10. The assembly of claim 6 wherein the D-ring is swivel attached to the slide with a D-ring bolt.

11. A shoulder belt height adjuster assembly for a motor vehicle, the assembly comprising:

a guide rail including a plurality of fixed rail teeth disposed along at least one longitudinal portion;

a slide including an aperture formed therein for slidably receiving the guide rail along the longitudinal portion, the slide including a plurality of fixed slide teeth disposed on an interior slide surface, wherein the fixed slide teeth comprise a rounded configuration; and

a biasing member operably attached to the slide aperture for selectively engaging at least one of the fixed slide teeth into at least one of the fixed rail teeth;

wherein said engagement prevents slidable movement of the slide relative to the guide rail in a downward direction.

12. The assembly of claim 11 wherein the biasing member comprises at least one bend formation.

13. The assembly of claim 11 wherein the biasing member is positioned substantially within the slider aperture.

14. The assembly of claim 11 further comprising:

at least one mount for operable attaching the assembly to the motor vehicle; and

a D-ring operably attached to the slide and to a shoulder belt.

15. The assembly of claim 14 wherein the D-ring is swivel attached to the slide with a D-ring bolt.
