Abstract

An arrangement for mounting a restraint belt mounted vehicle seat to a floor of an automotive vehicle is provided. The arrangement includes a floor rail supporting the vehicle seat, a load cell providing a supporting platform for the floor rail above the vehicle floor, a force transmittal member connected to the floor rail, a headed fastener connected to the vehicle floor, and a capture member connected to the vehicle floor by the fastener, the capture member in normal operational conditions having a clearance with the force transmittal member. In a predefined vehicle crash situation the force transmittal member is moved to an interference with the capture member retaining the floor rail to the vehicle floor.

Claims

1. An arrangement for mounting a restraint belt mounted vehicle seat to a floor of an automotive vehicle comprising:

a floor rail supporting said vehicle seat;

a load cell providing a supporting platform for said floor rail above the vehicle floor;

a force transmittal member connected to said floor rail;

a headed fastener connected to the vehicle floor;

and

a capture member connected to the vehicle floor by said fastener, said capture member in normal operational conditions having a clearance with said force transmittal member and wherein in a predefined vehicle crash situation said force transmittal member is moved to an interference with said capture member retaining said floor rail to the vehicle floor.

2. An arrangement as described in claim 1, wherein said floor rail mounts a fore and aft adjustable seat rail.

3. An arrangement as described in claim 1, wherein said capture member has a U-shaped cross-sectional shape with an extending flange.

4. An arrangement as described in claim 3, wherein said capture member has an aperture for allowing insertion of said fastener and wherein said force transmittal member has an aperture positioned adjacent said capture member underneath said extending flange of said capture member.

5. An arrangement as described in claim 1, wherein said fastener connects a lower riser to the vehicle floor and said lower riser supports said load cell.

6. An arrangement as described in claim 5, wherein said lower riser cantileverally supports said floor rail.

7. An arrangement as described in claim 1, having two fasteners, two force transmittal members and two capture members for retaining said floor rail adjacent the front and rear ends of said floor rail.

8. An arrangement for mounting a belt mounted vehicle seat to a floor of an automotive vehicle comprising:

a floor rail for supporting a fore and aft adjustable seat rail on top thereof with a vehicle seat being fixably connected to said seat rail;

a lower riser fixably connected to the vehicle floor;

a load cell fixably connected to said lower riser and said floor rail and supporting said floor rail above said lower riser;

a force transmittal member connected to said floor rail having an aperture;

a headed fastener inserted through said aperture of said force transmittal member and connecting said lower riser to the vehicle floor;

a capture member having a U-shaped cross-sectional shape with extending flanges and an aperture allowing insertion of said fastener to connect said capture member with the vehicle floor, and wherein said force transmittal member aperture is positioned adjacent said extending flanges of said capture member, and wherein said capture member in normal operational conditions having a clearance with said force transmittal member, and wherein in a predefined vehicle crash situation said force transmittal member is moved to an interference with said capture member, retaining said floor rail to the vehicle floor.

9. A method of mounting a belt mounted vehicle seat to a floor of an automotive vehicle comprising:

supporting a vehicle seat on a floor rail;

providing a load cell as a supporting platform for said floor rail above the vehicle floor;

connecting a force transmittal member to said floor rail;

connecting a headed fastener to the vehicle floor; and

connecting to the vehicle floor with said fastener a capture member having a clearance with the force transmittal member and in a predefined crash situation wherein said force transmittal member is moved to an interference with said capture member retaining said floor rail to said vehicle seat.
