摘要： A headrest assembly for a vehicle seat. The headrest assembly includes a support bracket having a first engagement section and a moveable bracket movable between first and second positions. The headrest assembly further includes a pawl defining a cam surface. The pawl has a second engagement section and is pivotable between an engaged position, with the second engagement section engaging the first engagement section, and a disengaged position, with the second engagement section spaced from the first engagement section. The headrest assembly further includes a first tab selectively engaging and guiding the pawl into the engaged position, and a second tab selectively engaging and guiding the pawl into the disengaged position as the moveable bracket moves between the first and second positions. The headrest assembly further includes a biasing member engaging the cam surface to continuously bias the pawl into both of the engaged and disengaged positions.

摘要： A fluid routing device (20) directs the transportation of a fluid. The fluid routing device includes a housing (22) having an opening (40) with a seat (38), and a valve (42) opening and closing the opening. The valve includes a first permanent magnet (56) having a first magnetic coercivity and a first polarity and a second permanent magnet (58) having a second magnetic coercivity lower than the first magnetic coercivity of the first permanent magnet such that the second permanent magnet has a second polarity capable of switching between a complimentary configuration oriented in a common direction as the first polarity, and a reversed configuration oriented in an opposite direction from the first polarity. A coil (59) surrounds at least the second permanent magnet. The coil is configured to orient the second polarity in the complimentary configuration when electric current passes in a first direction and in the reversed configuration when electric current passes in a second direction.

摘要： One embodiment of a lumbar support system includes one or more air cells adapted to be mounted to a vehicle seat assembly, a pump selectively inflating the air cells, and a valve fluidly connected between the pump and the air cells. The valve includes a body defining a pair of cavities corresponding with each of the air cells. The valve further includes an inflate plunger movable in one of the cavities to selectively open the cavity and a deflate plunger movable in the other cavity to selectively open the other cavity. Furthermore, the valve includes an actuator movably coupled to the body between a first operational position to inflate the air cell, and a second operational position to deflate the air cell. An electrical switch is electrically coupled to an electrical input of the pump and closed when the actuator is moved to the first or second operational positions.
