Abstract

A seatbelt web guide assembly is adapted to be fixed to a seat back and comprises a web guide in the shape of a loop and a track base adapted to be fixed to a seat back. The track base has a housing and a sliding element. The housing is adapted to be fixed to the seat back and defines a sliding axis. A sliding element is slideably disposed in a guide feature of the housing defining the sliding axis. The web guide is connected to the sliding element for movement therewith along the sliding axis. A spring is disposed between the housing and the sliding element, biasing the sliding element relative to the housing.

First claim

The invention claimed is:

1. A seatbelt web guide assembly of adapted to be fixed to a seat back comprising:
a web guide in the shape of a loop; and
a track base including:
a housing adapted to be fixed to the seat back and defining a sliding axis;
a sliding element slideably disposed in an axially extending guide feature in the housing;
the web guide connected to the sliding element for movement therewith along the sliding axis; and
a spring disposed between the housing and the sliding element and the spring biasing the sliding element relative to the housing,
wherein
the sliding element includes a substantially planar guide plate; and
the housing defining as a first guide feature a groove receiving the guide plate for translation therein along the sliding axis.

2. The web guide assembly of claim 1 wherein the housing includes an end cap covering the groove and restricting travel of the guide plate.

3. The web guide assembly of claim 1 wherein the sliding element further includes a slider disposed in a channel defined as a second guide feature by the housing with the slider being disposed between the spring and the guide plate and the slider is fixed to the guide plate for axial translation therewith.

4. The web guide assembly of claim 3 wherein the spring is a compression coil spring.

5. The web guide assembly of claim 4 wherein the housing includes an end cap disposed on an end of the housing and the end cap covers the groove and the channel and restricts travel of the guide plate and is engaged by the spring.

6. The web guide assembly of claim 5 wherein the slider is substantially spherical in shape and has a first post received by an aperture in the guide plate and has a second post received by an end of the spring.

7. The web guide assembly of claim 6 wherein the first post is further received by the web guide.

8. A seatbelt web guide assembly adapted to be fixed to a seat back comprising:
a web guide in the shape of a loop; and
a track base including:
a housing adapted to be fixed to the seat back and defining a sliding axis;
a sliding element including a slider slideably disposed in a channel defined by the housing;
the web guide connected to the slider for movement therewith along the sliding axis; and
a spring disposed between the housing and the slider and the spring biasing the slider relative to the housing,
wherein the sliding element further includes a substantially planar guide plate slideably disposed in a groove formed in the housing for translation therein along the sliding axis and further disposed between the slider and the web guide.

9. The web guide assembly of claim 8 wherein the spring is a compression coil spring.

10. The web guide assembly of claim 9 wherein the housing includes an end cap disposed on an end of the housing and the end cap covers the groove and the channel and restricts travel of the guide plate and is engaged by the spring.

11. The web guide assembly of claim 9 wherein the slider is substantially spherical in shape and has a first post received by an aperture in the web guide and has a second post received by an end of the spring.

12. The web guide assembly of claim 11 wherein the first post is further received by the web guide.

13. A seatbelt web guide assembly adapted to be fixed to a seat back comprising:
a web guide in the shape of a loop; and
a track base including:
a housing adapted to be fixed to the seat back and defining a sliding axis;
a sliding element including a slider slideably disposed in a channel defined by the housing and a substantially planar guide plate connected to the slider and slideably disposed in a groove formed in the housing for translation therein along the sliding axis;
the web guide connected to the slider for movement therewith along the sliding axis; and
a spring disposed between the housing and the slider and the spring biasing the slider relative to the housing.

14. The web guide assembly of claim 13 wherein the spring is a compression coil spring.

15. The web guide assembly of claim 14 wherein the housing includes an end cap disposed on an end of the housing and the end cap covers the groove and the channel and restricts travel of the guide plate and is engaged by the spring.

16. The web guide assembly of claim 14 wherein the slider is substantially spherical in shape and has a first post received by an aperture in the web guide and has a second post received by an end of the spring.

17. The web guide assembly of claim 16 wherein the first post is further received by the web guide.
