Abstract

A web management system includes a base that is configured to be secured to the seat of a vehicle. A retraction member has a first end and a second end. The first end is fixedly secured to an anchor attached to the base. The retraction member is configured to expand and retract in length between a first length and a shorter second length. The expansion and retraction are biased in favor of retraction to the second length. A web having at least a portion is fixedly secured to the base. A roller is attached to the second end of the retraction member. The roller is configured to slidably couple the web to the retraction member. Retraction of the retraction member takes up slack in the web.

First claim

The invention claimed is:

1. A system, comprising:
a child safety seat configured to secure to a vehicle, wherein the seat defines one or more strap apertures;
a plurality of restraining straps extending through the strap apertures in the seat, wherein the restraining straps are configured to hold an occupant in the seat, wherein each of the restraining straps has a first end anchored to the seat and a second end extending through one of the strap apertures;
a restraint adjustment strap connected to the second ends of the restraining straps, wherein the restraint adjustment strap is configured to tighten the restraining straps when pulled from a stowed state to an extended state; and
a retraction member having a first end anchored to the seat and a second end coupled to the restraint adjustment strap, wherein the retraction member is made of an elastic material that stretches to a first length and retracts to a second length that is shorter than the first length, wherein the retraction member is biased to retract from the first length to the second length to pull the restraint adjustment strap from the extended state to the stowed state.

2. The system of claim 1 , wherein the retraction member includes elastic material biased to pull the restraint adjustment strap from the extended state to the stowed state.

3. The system of claim 2 , further comprising:
an adjustor anchored to the seat, wherein the adjustor selectively secures the restraint adjustment strap.

4. The system of claim 3 , further comprising:
a roller attached to the retraction member; and
wherein the restraint adjustment strap has a looped back section that passes through the roller and is anchored to the seat.

5. The system of claim 4 , further comprising:
a splitter plate connecting the restraining straps to the restraint adjustment strap.

6. The system of claim 4 , wherein the roller is ring-shaped with longitudinally extending sections connected to curved sections.

7. The system of claim 4 , wherein the restraint adjustment strap extends from the adjustor and into the seat where the restraint adjustment strap passes through the roller, the restraint adjustment strap extends from the roller back towards the adjustor where the restraint adjustment strap is anchored to the seat at the adjustor.

8. The system of claim 7 , where:
the seat includes an anchor point and a redirection point;
the retraction member is anchored to the redirection point and looped around the anchor point; and
the retraction member extends from the anchor point and is redirected by the redirection point towards the restraint adjustment strap.

9. The system of claim 1 , further comprising:
a multi-point buckle coupled to the restraining straps.

10. The system of claim 1 , wherein:
the seat defines an internal cavity;
the restraining straps extend through the strap apertures into the internal cavity of the seat; and
the restraint adjustment strap is disposed inside the internal cavity.

11. A method, comprising:
securing an occupant in a safety seat by buckling restraining straps to the seat with a multi-point buckle, wherein the restraining straps are connected to a restraint adjustment strap that extends through an adaptor, wherein the seat includes a roller attached to a retraction member, wherein the restraint adjustment strap is looped back through the roller and is anchored to the seat at the adaptor;
tightening the restraining straps by pulling the restraint adjustment strap from a stowed state to an extended state, wherein the retraction member is biased to pull the restraint adjustment strap to the stowed state, wherein the retraction member is an elastic strap that stretches to a first length and retracts to a second length that is shorter than the first length, wherein said tightening includes stretching the retraction member from the second length to at least the first length;
holding the restraining straps in a tightened state by securing the restraint adjustment strap with the adaptor; and
moving the restraint adjustment strap to the stowed state with the retraction member by releasing the restraint adjustment strap, wherein said moving includes shrinking the retraction member from the first length to the second length to pull the restraint adjustment strap to the stowed state.

12. The method of claim 11 , further comprising:
securing the safety seat to a passenger seat in a vehicle.

13. A system, comprising:
a child safety seat configured to secure to a vehicle, wherein the seat defines one or more strap apertures;
a plurality of restraining straps extending through the strap apertures in the seat, wherein the restraining straps are configured to hold an occupant in the seat, wherein each of the restraining straps has a first end anchored to the seat and a second end extending through one of the strap apertures;
a restraint adjustment strap connected to the second ends of the restraining straps, wherein the restraint adjustment strap is configured to tighten the restraining straps when pulled from a stowed state to an extended state;
a retraction member having a first end anchored to the seat and a second end coupled to the restraint adjustment strap, wherein the retraction member is biased to pull the restraint adjustment strap from the extended state to the stowed state;
wherein the retraction member includes elastic material biased to pull the restraint adjustment strap from the extended state to the stowed state;
an adjustor anchored to the seat, wherein the adjustor selectively secures the restraint adjustment strap;
a roller attached to the retraction member; and
wherein the restraint adjustment strap has a looped back section that passes through the roller and is anchored to the seat.

14. The system of claim 13 , further comprising:
a splitter plate connecting the restraining straps to the restraint adjustment strap.

15. The system of claim 13 , wherein the roller is ring-shaped with longitudinally extending sections connected to curved sections.

16. The system of claim 13 , wherein the restraint adjustment strap extends from the adjustor and into the seat where the restraint adjustment strap passes through the roller, the restraint adjustment strap extends from the roller back towards the adjustor where the restraint adjustment strap is anchored to the seat at the adjustor.

17. The system of claim 16 , where:
the seat includes an anchor point and a redirection point;
the retraction member is anchored to the redirection point and looped around the anchor point; and
the retraction member extends from the anchor point and is redirected by the redirection point towards the restraint adjustment strap.

18. The system of claim 13 , further comprising:
a multi-point buckle coupled to the restraining straps.

19. The system of claim 13 , wherein:
the seat defines an internal cavity;
the restraining straps extend through the strap apertures into the internal cavity of the seat; and
the restraint adjustment strap is disposed inside the internal cavity.
