A tunable vibration dampener includes a support including a first support wall and a second support wall spaced from the first support wall and a mass suspended between the first support wall and the second support wall. The mass has a first side surface and a second side surface. A first support system having a support member connects the first side surface and the first support wall and a second support system having a support element connects the second side surface and the second support wall. At least one of the support member and the support element is adjustable to establish a selected attenuation frequency for the tunable vibration dampener.

A multi-actuator capable vehicle headrest includes a headrest support and a multi-cam release mechanism mounted to the headrest support. The multi-cam release mechanism includes a first cam and a second cam. A headrest shell member is pivotally mounted to the headrest support through the multi-cam release mechanism. An actuator is mounted to the headrest shell member. The actuator includes a first actuator portion operable to disengage the multi-cam release mechanism based on a first input and a second actuator portion operable to disengage the multi-cam release mechanism based on a second input that is distinct from the first input allowing the multi-actuator capable vehicle headrest to transition between a deployed configuration and a folded configuration.

Multi-actuator capable headrest

A vehicle seat including a seatback, and headrest including a shell member. A release mechanism is mounted to the shell member. The release mechanism selectively locks the headrest relative to the seatback. An actuator system extends between the seatback and the headrest. The actuator system includes a sleeve having a first end fixedly connected relative to the seatback, a second end fixedly connected relative to the headrest shell, and an intermediate portion defining a longitudinal length of the sleeve, and a cable extending through the sleeve. The cable has a first end section arranged in the seatback and a second end section coupled to the release mechanism. The longitudinal length of the sleeve includes a first dimension when the seatback is in an upright position and the longitudinal length has a second, longer dimension, when the seatback is in a folded configuration.

A ventilation system for a seat cushion comprises a reticulated ventilation manifold disposed in the seat cushion. The ventilation manifold has an inlet disposed adjacent a first side of the cushion and a plurality of manifold ducts extending from the inlet to terminate in outlets disposed at or near openings in a second side of the cushion. A fan motor is attached adjacent the first side of the cushion and has a fan outlet in fluid communication with the inlet of the ventilation manifold. The fan motor operates to apply a positive or a negative pressure, via the fan outlet to the ventilation manifold to supply air through the ventilation manifold and the cushion.

Seat assembly

A seat assembly includes a seat frame, a sub frame, an electric motor, a transmission, and a flexible drive shaft. The seat frame includes a front support portion and supports a bottom cushion. The sub frame has a top plate and a base plate. The top plate supports a front cushion and rotatably supports a screw gear. The electric motor includes a first output member and is fixedly mounted to the front support portion of the seat frame. The transmission includes an input member and a second output member. The transmission is fixedly mounted to the base plate of the sub frame. The second output member of the transmission is drivingly connected to the screw gear of the sub frame. The flexible drive shaft is drivingly connecting the first output member of the electric motor to the input member of the transmission.

An inertial latch for a motor vehicle armrest is rotatably connected to a a bracket mounted to a support structure; an armrest interfacing component is disposed in an arcuate slot in the bracket, the slot extending from a first to a second end; a primary pawl rotatable from a first to a second position and limiting motion of the interfacing component in the slot; a secondary pawl rotatable from a third position to a fourth position and limiting motion of the primary pawl; a stop limits motion of the secondary pawl. The armrest articulates from a closed to an open position, the interfacing component moves through the entire slot when the primary pawl is in the first position, the interfacing component is held within a portion less than the entire slot when the primary pawl is in the second position, and the interfacing component is releasable from the portion.
