Abstract: A seat assembly includes a seat, one or more sensor assemblies, and/or an electronic control unit that may be connected to the one or more sensor assemblies. The one or more sensor assemblies may provide information about a first position of the seat to the electronic control unit. The electronic control unit may be configured to receive a second position of the seat, and/or the electronic control unit may be configured to automatically move the seat to the second position without contacting other objects. The electronic control unit may include a second seat, and/or the electronic control unit may be configured to automatically move the second seat from a first second seat position to a second second seat position. The electronic control unit may be configured to determine a movement path of the seat according to information from the one or more sensor assemblies.

Abstract: A temperature control system for a vehicle seat includes a finish trim layer, a thermally conductive panel in thermal contact with the finish trim layer, a thermal device generating a temperature gradient, and a heat transfer structure connecting the panel and the thermal device. The panel and the heat transfer structure are adapted to together thermally conduct the quantity of heat between the finish trim layer and the thermal device.

Abstract: A vehicle seat controller is provided to control a front seat assembly and a rear seat assembly positioned directly behind of the front seat assembly. The vehicle seat controller programmed to receive a first input indicating whether the rear seat assembly is occupied and receive a second input indicating a position of the front seat assembly. The vehicle seat controller is programmed to provide a signal to an actuator to move the front seat assembly forward if the first input indicates the rear seat is occupied and the second input indicates the position exceeds a rearward travel threshold.

Abstract: A seat assembly having an occupant protection system. The occupant protection system may have a deployable shield. The deployable shield may extend around multiple sides of the seat assembly may extend at least partially around a front of a seat occupant when deployed, may be deployable along a dynamic deployment path based on a detected position of a seat occupant, or combinations thereof.

Abstract: A system and method for positioning a seat arrangement in a vehicle includes moving the seat arrangement forward by a first amount when a certain criteria are met. The criteria may include at least one criterion related to occupancy of a seat directly behind the seat arrangement and at least one criterion related to a likelihood of an impact into the vehicle from behind the seat arrangement. The method may also include not moving the seat arrangement forward by the first amount when at least one of the criteria is not met.

Abstract: A system and method for positioning a seat arrangement in a vehicle having a front seat arrangement and a rear seat arrangement includes moving the rear seat arrangement rearward relative to the vehicle when a plurality of criteria are met, including at least one criterion related to occupancy of the rear seat arrangement and at least one criterion related to a likelihood of impact into the vehicle from behind the vehicle. The rear seat arrangement is not moved rearward when at least one of the criteria is not met.

Abstract: A seat assembly having a headrest and a method of assembly. The headrest may be pivotally disposed on a support post and may have a support plate. The support plate may have first and second walls that have first and second holes, respectively, that may be disposed along the axis and that may receive the support post.

Abstract: A head restraint assembly is provided with a first guide member mounted proximate to a vehicle seat back. A second guide member is mounted to the first guide member for translation along the first guide member. A locking mechanism is mounted to the second guide member in cooperation with the first guide member for locking the second guide member relative to the first guide member. The first and second guide members are connected by at least one spherical bushing. A torsion spring is connected to the first guide member and oriented about the second guide member for locking the second guide member relative to the first guide member.

A locking mechanism is mounted to the second guide member in cooperation with the first guide member for locking the second guide member relative to the first guide member. The first and second guide members are the only guide members to minimize binding. The locking mechanism includes a torsion spring connected to the first guide member and oriented about the second guide member for locking the second guide member relative to the first guide member. A lever is mounted to the torsion spring for unlocking the torsion spring.

Abstract: A vehicle seat assembly having a seatback frame, an upper armature that is movable relative to the seatback frame and a head restraint mounted on the upper armature. A linkage assembly operatively interconnects the upper armature and an impact body such that movement of the impact body relative to the seatback frame acts on the linkage assembly to move the upper armature relative to the seatback frame to cause the head restraint to move toward the occupant. The linkage assembly includes a linkage and a coupler movably connected to the linkage. The coupler includes a first member movably connected to the seatback frame and a second member movably connected to the first member at a location below the upper end of the impact body.

Abstract: A head restraint assembly includes a post assembly which has a first post section, a second post section, and a cross member section connecting the first post section and the second post section. The first post section and the second post section are adapted to engage a vehicle seat. The head restraint includes a bun moveably attached to the post assembly, a first gear, and a motor that rotates the first gear in a clockwise or counter-clockwise direction. Rotation of the first gear drives a second gear which drives a third gear. Rotation of the second gear in a first direction causes movement of the bun to a tilted position while movement of the second gear in a second direction causes movement of the bun to an upright position.
