A drive bush configured to circumferentially rotate and drive a pair of wedge members in an eccentric space includes a cylindrical portion rotatably supported inside a boss portion of an internal tooth constituting member, a flange portion integrally formed at a first end portion in the axial direction of the cylindrical portion so as to face one side surface side of the wedge members, and a pushing portion integrally provided on the outer peripheral side of the flange portion, and configured to release a wedge effect by circumferentially pushing the wedge members. The inner surface of the cylindrical portion is integrally formed with a wall portion, and the wall portion is formed with, in the middle thereof, a female spline teeth meshing with the output shaft of a motor. The cylindrical portion, the wall portion including the female spline teeth and the flange portion have substantially the same thickness.

A seat assembly for use in an automotive vehicle includes a seat back pivotally coupled to a seat cushion and at least one link pivotally coupled between the seat cushion and a seat base. A detent assembly is rotatably coupled to the seat base, the detent assembly actuatable between a use condition for operatively coupling the at least one link and the detent assembly, and an override condition for decoupling the at least one link and the detent assembly. A linkage motor is operatively engaged with the detent assembly for pivoting the at least one link to move the seat assembly between a plurality of positions. Actuation of the detent assembly from the use condition to the override condition allows for manual pivoting of the at least one link to move the seat assembly between the plurality of positions in situations where the linkage motor is unable to be actuated.

The present disclosure is directed to a seat back frame that has a composite body. The composite body includes a first side member and a second side member positioned on opposite sides of the composite body. The first and second side members include a recliner assembly at a lower end of each member. Each recliner assembly includes a first bracket, a second bracket, and a recliner sub-assembly. Each recliner assembly is welded or otherwise coupled to an extension that extends away from the recliner assembly along a respective side of the composite body. The extension may be stamped steel having a first end that is closer to the recliner assembly and a second end that is spaced from the recliner assembly. The first end of the extension has a width that is greater than a width of the second end.

A lift mechanism for a vehicle seating assembly comprises a gear assembly that includes a first gear and a second gear. A mounting bracket is fixedly coupled to a vehicle and shares a common axis with the first gear, wherein the first and second gears are positionable in a fixedly coupled arrangement at an initial location relative to the mounting bracket or at a final location relative to the mounting bracket, such that, when the first and second gears are in the fixedly coupled arrangement at the initial location relative to the mounting bracket, the seating assembly is in a sitting position, and when the first and second gears are in the fixedly coupled arrangement at the final location relative to the mounting bracket, the seating assembly is in a standing position.

A seat for a motor vehicle, the seat comprising a backrest and a seating portion, the backrest being mounted to rotate relative to the seating portion about a substantially transverse axis, a hinge being provided for adjusting a tilt of the backrest relative to the seating portion about the substantially transverse axis, the seat being provided with a plurality of means for controlling a movement of the hinge, the seat further comprising an interface for controlling said movement of the hinge, the interface comprising a central portion and a peripheral portion, the peripheral portion being arranged around the central portion, the interface further comprising a plurality of recesses shaped to receive the plurality of means for controlling the movement of said hinge.

An aircraft seat includes an actuator and a movement transmission device. The transmission device includes a frame provided with an immobilizing portion and a drive shaft. The transmission device further includes a gear wheel provided with coupling teeth having inclined side walls and a sleeve with an immobilizing portion complementary to the immobilizing portion of the frame, and coupling teeth having inclined side walls. The transmission device also has an elastic member configured to push the sleeve. The stiffness of the elastic member and the inclination of the side walls of the coupling teeth of the gear wheel and sleeve are chosen such that, when a torque greater than a threshold torque is applied to the gear wheel, the sleeve slides on the drive shaft from a position of coupling the sleeve to the gear wheel to a position of immobilizing the sleeve relative to the frame.

A vehicle seat including a pivot bracket, a back frame, a linear adjustment mechanism, a striker, and a latch. The back frame is pivotally connected to the pivot bracket and configured to pivot about a pivot axis. The back frame includes a first end spaced apart from the and disposed below the pivot axis. The latch is configured to selectively attach the linear adjustment mechanism to the first end of the back frame so that as the first linear adjustment mechanism translates, the back frame pivots from a first use position and a second use position, and selectively detach the linear adjustment mechanism from the first end of the back frame so that the back frame is pivotable to a non-use position.

The present disclosure is directed to a seat back frame that has a composite body. The composite body includes a first side member and a second side member positioned on opposite sides of the composite body. The first and second side members include a recliner assembly at a lower end of each member. Each recliner assembly includes a first bracket, a second bracket, and a recliner sub-assembly. Each recliner assembly is welded or otherwise coupled to an extension that extends away from the recliner assembly along a respective side of the composite body. The extension may be stamped steel having a first end that is closer to the recliner assembly and a second end that is spaced from the recliner assembly. The first end of the extension has a width that is greater than a width of the second end.
