Vehicle seat track system
First Claim
1. A track system for coupling a seat within a vehicle, the seat including at least a seat cushion, the seat cushion including a central portion defining the portion of the seat cushion that experiences the greatest downward deflection when the seat cushion is occupied by an occupant, the track system comprising:
- a first track arrangement configured to be coupled to the seat cushion and the vehicle;
a second track arrangement configured to be coupled to the seat cushion and the vehicle so that the second track arrangement is parallel to and spaced apart from the first track arrangement; and
a motor coupled to the first track arrangement and the second track arrangement and comprising a first output including an axis of rotation generally parallel to the first track arrangement;
a gear box operably coupled to the first output of the motor, the first track arrangement, and the second track arrangement;
wherein the first track arrangement and the second track arrangement are configured to adjust the position of the seat cushion within the vehicle when the motor is operated; and
wherein each of the motor and the gear box are located closer to the first track arrangement than to the second track arrangement.

Abstract
A track system for coupling a seat having a seat cushion within a vehicle includes a first track arrangement, a second track arrangement, a motor, and a gear box. The first track arrangement is configured to be coupled to the seat cushion and the vehicle. The second track arrangement is configured to be coupled to the seat cushion and the vehicle so that the second track arrangement is parallel to and spaced apart from the first track arrangement. The motor is coupled to the first track arrangement and the second track arrangement and comprises a first output that includes an axis of rotation generally parallel to the first track arrangement. The gear box is operably coupled to the first output of the motor, the first track arrangement, and the second track arrangement. The first track arrangement and the second track arrangement are configured to adjust the position of the seat cushion within the vehicle when the motor is operated. Each of the motor and the gear box are located closer to the first track arrangement than to the second track arrangement.
