The invention relates to a motor vehicle seat for motor vehicles comprising an adjustment device for a backrest head adjustment, the motor vehicle seat having a backrest, which has a backrest frame as the first component of the backrest head adjustment and a backrest head as the second component of the backrest head adjustment, and an actuator. The backrest head is pivotably connected to the backrest frame and the actuator has a driving element and a movable element, the actuator being connected to the backrest frame and the backrest head and it being possible to carry out a linear movement by means of the actuator. The driving element of the actuator is rigidly connected to the backrest frame or backrest head and the movable element of the actuator has a guide element which engages in a guide arranged on the backrest frame or backrest head.

A fold and dive seat for a vehicle that achieves a fatigue reduction posture is provided. The seat includes a tip up-extension mechanism that enable stipping-up and extension of the front end of a seat cushion and a seatback reclining mechanism for the fold and dive seat so that tipping-up for lifting the front end of the seat cushion and extension for extending the front end forward are performed simultaneously performed when the seatback reclining is performed.

A recliner mechanism having a first plate, a second plate, and at least one pawl. The first plate has a first set of teeth. The second plate has a second set of teeth. The pawl that has a set of pawl teeth that engage the first set of teeth and the second set of teeth to inhibit rotation of the second plate with respect to the first plate.

A motor vehicle includes a structural element and a seat having at least two separate and independent seat portions, each of the seat portions being configured to support a part of a user's body and being independently coupled to the structural element in a movable manner relative to the structural element with three degrees of freedom including two translations in a plane along respective orthogonal axes and a rotation around a further axis orthogonal to said plane.

Clutch-based adjustment mechanism for motorized multi-way seat adjustment An adjustment mechanism comprises multiplescrew shafts (111, 112, 113) and a motor (150) for driving the screw shafts. Further, the adjustment mechanism comprises a clutch mechanism (160) for selectively engaging the motor (150) with one or more of the screw shafts (111, 112, 113). A rotation of one or more of the screw shafts (111, 12, 113) caused by the motor (150) translates into adjustment of the seat according to a first degree of freedom. A rotation of one or more others of the screw shafts (111, 12, 113) caused by the motor (150) translates into adjustment of the seat according to a second degree of freedom.

The invention concerns a seat back (10) for an article of adjustable furniture comprising: a frame (12), at least one movable support section (14, 80) mounted for angular adjustment with respect to the frame; cam means (64) associated with one of the frame and the movable support section, cam follower means (58) associated with the other of the frame and the movable support section; actuator means (38) for moving said cam means or cam follower means associated with the frame with respect to the frame; whereby movement of said actuator means effects relative movement of said cam means with respect to said cam follower means and said relative movement effects angular adjustment of said support section relative to the frame to alter the seat back configuration. The present invention contemplates embodiments where the support section(s) comprise(s) an adjustable head rest (14), an adjustable lumbar support (80) or both.

Seat assemblies including a substantially perpendicular pull actuator release are described. The seat assemblies can include a seat and a seat recline mechanism. The seat can include a back portion and a seat pan. The seat recline mechanism can include a gas spring, a control cable, an actuator, a frame, and a lever. The gas spring can include a release mechanism. The actuator can couple to a first end of the control cable. The lever can include a pivot location, a first arm, and a second arm. The first arm can couple to the second end of the control cable. The lever can respond to a pulling force exerted by the actuator on the control cable by rotating about the pivot location such that the second arm engages the release mechanism of the gas spring to allow the back portion to rotate relative to the seat pan.
