Abstract

A web position and attenuation apparatus includes an elongated body extending in a longitudinal direction between opposite ends thereof, a bracket mounted to one of the opposite ends of the elongated body and configured to be affixed to a frame of a movable vehicle, a web coupling member slidably received on the elongated body and positionable along the elongated body. The web coupling member defines a first web slot, and a flexible web extends through the first web slot. The elongated body attenuates forces applied by the flexible web to the web coupling member in non-parallel directions relative to the longitudinal direction by elastically deforming in the non-parallel directions.

First claim

What is claimed is:

1. A web position and attenuation apparatus, comprising:
an elongated body extending in a longitudinal direction between opposite ends thereof,
a first bracket mounted to one of the opposite ends of the elongated body and configured to be affixed to a frame of a movable vehicle,
a web coupling member slidably received on the elongated body and positionable along the elongated body, the web coupling member defining a first web slot, and
a flexible web extending through the first web slot, the flexible web configured to restrain an occupant of a vehicle seat mounted within the vehicle,
the elongated body attenuating forces applied by the flexible web to the web coupling member in non-parallel directions relative to the longitudinal direction by elastically deforming the elongated body in the non-parallel directions.

2. The web position and attenuation apparatus of claim 1 , further comprising a second bracket mounted to the other of the opposite ends of the elongated body and configured to be affixed to the frame of the movable vehicle.

3. The web position and attenuation apparatus of claim 1 , wherein the elongated body comprises a planar body defining a planar surface on at least one face thereof that extends in the longitudinal direction between the opposite ends thereof,
and wherein the non-parallel directions in which the elongated body is elastically deformable are non-parallel directions relative to the first planar surface in an area of the planar body at which the web coupling member is positioned.

4. The web position and attenuation apparatus of claim 3 , wherein the planar surface extends between opposite sides of the planar body and defines a transverse direction between the opposite sides,
and wherein the first web slot comprises an elongated slot extending in a direction parallel to the transverse direction adjacent to the planar surface.

5. The web position and attenuation apparatus of claim 4 , wherein the elongated body is vertically oriented with the one of the opposite ends of the elongated body positioned above the other of the opposite ends of the elongated body,
and wherein the first bracket defines a second web slot therethrough, the flexible web extending through the second web slot, downwardly along the planar surface of the elongated member between the second web slot and the web coupling member, and through the first web slot of the web coupling member.

6. The web position and attenuation apparatus of claim 5 wherein one end of the flexible web extending from the second web slot is affixed to the first bracket and an opposite end of the flexible web extending from the first web slot is configured to be affixed to the vehicle seat.

7. The web position and attenuation apparatus of claim 5 further comprising a locking web retractor configured to be mounted to the vehicle,
and wherein one end of the flexible web extending from the second web slot is attached to a rotatable spool of the web retractor and an opposite end of the flexible web extending from the first web slot is configured to be affixed to the vehicle seat.

8. A web position and attenuation apparatus, comprising:
an elongated body having a first end, a second end opposite the first end and a first surface extending longitudinally between the first and second ends with a plurality of longitudinally spaced-apart protrusions extending therefrom,
a first bracket mounted to the first end of the elongated body and configured to be affixed to a frame of a movable vehicle,
a second bracket mounted to the second end of the elongated body and configured to be affixed to the frame of a movable vehicle, and
a web coupling member slidably received on the elongated body and defining a web slot configured to receive a flexible web therethrough for restraining an occupant of a vehicle seat mounted within the vehicle, the web coupling member discretely positionable longitudinally along the elongated body between adjacent ones of the plurality of spaced-apart protrusions, the elongated body elastically deformable in non-parallel directions relative to the first surface in an area of the elongated body in which the web coupling member is discretely positioned to attenuate forces applied in the non-parallel directions to the web coupling member.

9. The web position and attenuation apparatus of claim 8 wherein the web coupling member defines an opening sized to slidably receive the elongated body therethrough, the elongated body longitudinally movable relative to the opening to discretely position the opening between adjacent ones of the plurality of spaced-apart protrusions.

10. The web position and attenuation apparatus of claim 9 wherein the each of the plurality of protrusions is sized to abut the web coupling member adjacent to at least a portion of the opening defined therethrough,
and wherein at least one of the web coupling member and each of the plurality of protrusions is elastically deformable to allow forced passage thereby of the web coupling member as the web coupling member is longitudinally moved along the elongated body to one of a plurality of discrete positions each defined between different adjacent ones of the plurality of protrusions.

11. The web position and attenuation apparatus of claim 10 , wherein the elongated body comprises an elongated planar strip with the first surface being a first planar surface and the elongated planar strip having a second planar surface opposite the first planar surface, each of the first and second planar surfaces having a length defined between the first and second ends of the elongated body and a width defined between opposite sides of the elongated planar strip,
and wherein the web slot comprises a first linear slot adjacent to the first or the second planar surface of the elongated body and extending transversely relative to the width of the first or the second planar surface.

12. The web position and attenuation apparatus of claim 11 wherein at least one of the plurality of protrusions comprises a rib normal to a plane defined by the first planar surface and extending across the width of the first planar surface.

13. The web position and attenuation apparatus of claim 11 further comprising at least one protrusion extending from the second planar surface of the elongated planar strip.

14. The web position and attenuation apparatus of claim 11 wherein the opening defined through the web coupling member comprises a second linear slot parallel with the first linear slot.

15. A web position and attenuation apparatus, comprising:
an elongated body extending in a longitudinal direction between a first end a second end thereof, the second end opposite the first end,
a mounting pin extending transversely through the elongated body at or near the first end thereof,
a first bracket defining a pair of channels sized to receive therein opposite ends of the mounting pin such that the first end of the elongated body is pivotable relative to the first bracket about the mounting pin, the first bracket configured to be affixed to a frame of a movable vehicle, and
a web coupling member slidably received on the elongated body and positionable along the elongated body, the web coupling member defining a first web slot configured to receive a flexible web therethrough for restraining an occupant of a vehicle seat mounted within the vehicle, the elongated body elastically deformable in non-parallel directions relative to the longitudinal direction of the elongated body to attenuate forces applied in the non-parallel directions to the web coupling member.
