Abstract

The seating system of the preferred embodiment of the invention has been specifically designed for a vehicle having a deceleration sensor adapted to sense a deceleration event of the vehicle. The seating system of this preferred embodiment includes a seat assembly, a tilting mechanism adapted to tilt the seat assembly, and a control unit coupled to the deceleration sensor and adapted to activate the tilting mechanism upon the sensing of a deceleration event.

Claims

1. A method of tilting a seat assembly of a vehicle having a seat section with a front portion and a rear portion and a tilting mechanism adapted to allow displacement of the front portion in an upward direction relative to the vehicle and to allow displacement of the rear portion in a downward direction relative to the vehicle, the method comprising the act of tilting the seat assembly upon the sensing of a deceleration event based on the following rules:

(a) if the rear portion of the seat section has not already been positioned to the furthermost downward position prior to the deceleration event and the front portion of the seat section has not already been positioned to the furthermost upward position, then simultaneously displacing the front portion in the upward direction relative to the vehicle and displacing the rear portion in the downward direction relative to the vehicle;

(b) if the rear portion of the seat section has already been positioned to the furthermost downward position prior to the deceleration event, then displacing the front portion in the upward direction relative to the vehicle; and

(c) if the front portion of the seat section has already been positioned to the furthermost upward position, then displacing the rear portion in the downward direction relative to the vehicle.

2. The method of claim 1 further comprising the act of activating an inflatable restraint system upon the sensing of a deceleration event.

3. The method of claim 1 further including providing a deceleration threshold for the deceleration event, wherein said tilting act includes tilting the seat assembly upon the sensing of a deceleration event with a magnitude greater than the deceleration threshold.
