A vehicle seat assembly including a vehicle seat mounted on a spring suspension system, the seat assembly having a safe mode into which it can be placed when the seat is unoccupied to avoid damage to the spring suspension system due to forces generated within the suspension system of an unoccupied seat. The seat assembly is configured to be placed in communication with a control system of an associated vehicle in which it is mounted and to invoke the safe mode in dependence on the vehicle being placed in a predetermined operating mode of the vehicle which is indicative that the seat will be unoccupied.

A headrest assembly includes a linkage system that is at least partially disposed within a housing. The linkage system is operable between fore and aft positions relative to the housing. An adjustable cover assembly includes a first member coupled to the linkage system for movement therewith, and a second member pivotally coupled to the first member. The second member includes an engagement flange configured to contact a portion of the housing to pivot the second member rearwardly as the adjustable cover assembly is driven outward by the linkage system during the positioning of a headrest bun.

A multi-linkage hinge assembly is provided for pivoting a seat cushion between flat and upright positions. The hinge assembly includes a base bracket, a seat bracket having a support surface, a front linkage member pivotally attached between the seat bracket and base bracket, a rear linkage assembly having a lower linkage member pivotally attached to an upper linkage member, and a tie linkage connecting the front linkage member to the rear linkage assembly. The tie linkage synchronizes movement of the front linkage and rear linkage assembly when the hinge is operated to move between an upright and flat position.

A seat module attached to a seat having mechanical parts for seat actuation in a motor vehicle includes at least one mechanical control cable for the seat actuation, and a module plate formed with a mounting feature for attaching to the seat and a retention feature for attaching the mechanical control cable. An end portion of the mechanical control cable is temporarily stowed on the module plate in a pre-assembled state where the mechanical control cable is attached to the module plate, and the end portion of the mechanical control cable is connected to the mechanical parts of the seat in an assembled state where the module plate with the attached mechanical control cable is securely mounted to the seat.

A seat cushion extension apparatus for a vehicle seat includes an extension unit slidable from a front end portion of a seat frame in a vehicle to a position disposed forwards of the front end portion of the seat frame, locking units for locking the extension unit with respect to the seat frame at a locking position, and allowing the extension unit to be slidable such that the extension unit protrudes forwards of the seat frame at a release position, and a lever for controlling the locking units between the locking position and the release position. The extension unit is supported by guide shafts to be movable forwards and rearwards in housings fixed to the seat frame. The guide shafts are locked in the housings at the locking position and are movable with respect to the seat frame at the release position.

A weight sensing mechanism for an aircraft seat pan configured to adjust seat pan recline force and including a gas spring arranged between a fixed seat frame member and a movable seat pan member, the gas spring arranged to compress as the seat pan reclines in response to a load on the seat pan, and unloads upon removal of the load on the seat pan to assist in returning the seat pan to upright, and a helper spring positioned forward of and coaxially with the gas spring arranged to deflect under any load on the seat pan. A recline-capable seat pan assembly including a passenger body weight sensing mechanism.

In a vehicle seat including a first member and a second member allowed to turn relative to the first member to thereby shift between a first state in which the second member faces the first member and a second state in which the second member is farther from the first member than in the first state, a first electric device is provided in the first member, a second electric device is provided in the second member, a first electric wire is connected to the first electric device, a second electric wire is connected to the second electric device, and a tying part is provided which ties the first electric wire and the second electric wire together into a bundle. The tying part is fixed to the first member.

A moving and locking device for a vehicle seat includes: a lower frame mounted on a bottom surface of a seat cushion; a plurality of wheels disposed underneath the lower frame in such a manner that the plurality of wheels roll on a floor panel; and a vacuum adsorption device disposed inside the lower frame and configured to be adsorbed on the floor panel by vacuum force. The vehicle seat is configured to be moved to the desired position through the rolling motion of the plurality of wheels, and configured to be locked at the desired position through vacuum adsorption of the vacuum adsorption device on the floor panel.

Provided is a belt assist device having a compact configuration and being configured to move a seatbelt to an easily reachable position. A vehicle seat includes a belt assist device attached to a lateral portion of a seat back and configured to move a portion of a seatbelt placed on the lateral portion to the easily reachable position. The belt assist device includes a rotary member attached to a recessed housing portion of the lateral portion via a rotary shaft and configured to rotate up and down between a housing position at which the rotary member is housed in the seat back and a protruding position at which the rotary member rotates to protrude forward of the seat back to push out a portion of the seatbelt. The rotary member is disposed forward of a belt guide provided at the periphery of an upper end of the seat back.

A truck seat adapter which is designed to be positioned between the floor of the driver's compartment and the seat base of a driver's seat to enable the seat to be positioned rearwardly of the factory installed position to provide additional leg room for the driver or the passenger. The positioning of the adapter plate for the driver's seat enables the seat to be positioned so as to not interfere with the closing of the driver's door. In a second embodiment, the positioning of the adapter plate for the passenger's seat enables the seat to be positioned so as to not interfere with the closing of the passenger's door.
