A vehicle seat includes a movable portion, a first spring, a second spring, and a preloading device. The first spring is capable of exerting an elastic force to displace the movable portion, which is displaced in a first direction, toward the neutral position. The second spring is capable of exerting an elastic force to displace the movable portion, which is displaced in a second direction, toward the neutral position. The preloading device is capable varying at least one of an elastic force applied by the first spring to the movable portion placed in the neutral position or an elastic force applied by the second spring to the movable portion placed in the neutral position.

A motor vehicle seating system is provided. The seating system comprises two or more seats and a guide track extending between three or more spaced apart seating positions within an interior of the motor vehicle, wherein each of the seats is movably coupled to the guide track, such that the seats are movable between the seating positions. A seat, suitable for use in the motor vehicle seating system is also provided.

A network of rails for a vehicle includes a lateral rail that extends primarily along a lateral axis of the vehicle, a longitudinal rail that extends primarily along a longitudinal axis of the vehicle, and a circular rail that interacts with at least one of the lateral rail and the longitudinal rail.

A seating assembly comprising a shell assembly, a base assembly operably coupled to the shell assembly, and a control assembly including a handle. The control assembly comprises a spindle gear positioned within the base assembly, a gear plate disposed in the shell assembly proximate the spindle gear, a locking key configured to simultaneously engage the spindle gear and the gear plate, a locking leaf spring configured to bias the locking key into engagement with the spindle gear and the gear plate, and an actuator configured to withdraw the locking key from engagement with one of the gear plate and spindle gear and subsequently withdraw the locking key from engagement with the other of the gear plate and spindle gear.
