Abstract

An inertial lock assembly is disclosed. In various embodiments, the inertial lock assembly includes a tracking rod oriented with respect to a longitudinal axis, a housing slidably disposed about the tracking rod, the housing including an inner surface having a first portion extending from an apex to a first end spaced longitudinally from the apex, a first sliding member slidably disposed about the tracking rod and within the housing proximate the first portion of the inner surface and a first binding member slidably disposed about the tracking rod and within the housing, the first binding member positioned between the apex and the first sliding member.

First claim

What is claimed is:

1. An inertial lock assembly, comprising:
a tracking rod oriented with respect to a longitudinal axis;
a housing slidably disposed about the tracking rod, the housing including an inner surface having a first portion extending from an apex to a first end spaced longitudinally from the apex;
a first sliding member slidably disposed about the tracking rod and within the housing proximate the first portion of the inner surface;
a first binding member slidably disposed about the tracking rod and within the housing, the first binding member positioned between the apex and the first sliding member; and
a biasing member disposed within the housing and configured to bias the first binding member in a first direction opposite the apex.

2. The inertial lock assembly of claim 1 , further comprising a first washer disposed between the biasing member and the first binding member.

3. The inertial lock assembly of claim 1 , wherein the first binding member comprises a first plurality of ball bearings.

4. The inertial lock assembly of claim 3 , wherein the first sliding member comprises a first collar.

5. The inertial lock assembly of claim 1 , wherein the first portion defines a first conical section extending from the apex to the first end.

6. The inertial lock assembly of claim 5 , wherein the first conical section defines a first angle with respect to the longitudinal axis extending from the apex to the first end.

7. The inertial lock assembly of claim 1 , wherein the inner surface has a second portion extending from the apex to a second end spaced longitudinally from the apex, the apex being disposed intermediate the first end and the second end.

8. The inertial lock assembly of claim 7 , further comprising:
a second sliding member slidably disposed about the tracking rod and within the housing proximate the second portion of the inner surface; and
a second binding member slidably disposed about the tracking rod and within the housing, the second binding member positioned between the apex and the second sliding member.

9. The inertial lock assembly of claim 8 , wherein the second portion defines a second conical section extending from the apex to the second end.

10. The inertial lock assembly of claim 9 , wherein the second conical section defines a second angle with respect to the longitudinal axis extending from the apex to the second end.

11. The inertial lock assembly of claim 10 , further comprising a biasing member disposed within the housing and configured to bias the first binding member in a first direction opposite the apex and the second binding member in a second direction opposite the apex.

12. The inertial lock assembly of claim 11 , wherein the first binding member comprises a first plurality of ball bearings and the second binding member comprises a second plurality of ball bearings.

13. The inertial lock assembly of claim 12 , wherein the first sliding member comprises a first collar and the second sliding member comprises a second collar.

14. A seat assembly, comprising:
a seat frame having a longitudinal axis;
a tracking rod oriented with respect to the longitudinal axis, the tracking rod having a fore end connected to a fore member of the seat frame and an aft end connected to an aft member of the seat frame;
a housing slidably disposed about the tracking rod, the housing including an inner surface having a first portion extending from an apex to a first end spaced longitudinally from the apex and a second portion extending from the apex to a second end spaced longitudinally from the apex, the apex being disposed intermediate the first end and the second end;
a first sliding member slidably disposed about the tracking rod and within the housing proximate the first portion of the inner surface;
a second sliding member slidably disposed about the tracking rod and within the housing proximate the second portion of the inner surface;
a first binding member slidably disposed about the tracking rod and within the housing, the first binding member positioned between the apex and the first sliding member; and
a second binding member slidably disposed about the tracking rod and within the housing, the second binding member positioned between the apex and the second sliding member.

15. The seat assembly of claim 14 , wherein the first portion defines a first conical section extending from the apex to the first end and the second portion defines a second conical section extending from the apex to the second end.

16. A seating system for a vehicle, comprising:
a substructure configured for attachment to a floor of the vehicle;
a seat frame slidably engaged with the substructure, the seat frame configured to slide in a fore direction and an aft direction along a longitudinal axis;
a tracking rod oriented with respect to the longitudinal axis, the tracking rod having a fore end connected to a fore member of the seat frame and an aft end connected to an aft member of the seat frame;
a housing slidably disposed about the tracking rod, the housing including an inner surface having a first portion extending from an apex to a first end spaced longitudinally from the apex and a second portion extending from the apex to a second end spaced longitudinally from the apex, the apex being disposed intermediate the first end and the second end;
a first sliding member slidably disposed about the tracking rod and within the housing proximate the first portion of the inner surface;
a first binding member slidably disposed about the tracking rod and within the housing, the first binding member positioned between the apex and the first sliding member;
a second sliding member slidably disposed about the tracking rod and within the housing proximate the second portion of the inner surface; and
a second binding member slidably disposed about the tracking rod and within the housing, the second binding member positioned between the apex and the second sliding member.

17. The vehicle seating system of claim 16 , further comprising a first sleeve member positioned adjacent an aft portion of the housing and connected to the substructure and a second sleeve member positioned adjacent a fore portion of the housing and connected to the sub structure.

18. The vehicle seating system of claim 17 , wherein the first binding member comprises a first plurality of ball bearings and the second binding member comprises a second plurality of ball bearings and wherein the first sliding member comprises a first collar and the second sliding member comprises a second collar.
