In a seat reclining device, a seatback frame forming a skeleton of a seatback is coupled to a seat cushion frame to be rotatable about a shaft with respect to the seat cushion frame. One end portion of a first sliding bracket is rotatably coupled to a middle portion of the seatback frame by a driving unit. The other end portion of the first sliding bracket extends toward a vehicle body located behind the seatback. A second sliding bracket is mounted on the vehicle body located behind the seatback and extends toward the first sliding bracket in a front and rear longitudinal direction to be connected to the first sliding bracket. The second sliding bracket is configured to guide a sliding movement of the first sliding bracket while the first sliding bracket is being rotated.

The invention concerns an actuation mechanism for controlling the movement of an aircraft seat between an upright position and a bed position. The aircraft seat comprises a back rest and connected seat pan with an actuator for moving the seat between an upright position and a bed position. The seat pan comprises a cam follower (32). The cam follower (32) is arranged to move along a first cam path (38) when the aircraft seat is moved from the upright position to the bed position. It is further arranged to move along a second cam path (40) when the seat is moved from the bed position to the upright position.

The present invention concerns an aircraft seat. The aircraft seat comprises at least one moveable element, and a cam follower arrangement associated with the moveable element. The cam follower arrangement comprises a first cam follower and second cam follower attached to a common bogie. Spreading the load over two cam followers attached to a common bogie may reduce the wear on each individual cam follower. This reduction in wear may result in fewer maintenance tasks associated with the aircraft seat, and may make the aircraft seat more robust.

An embodiment seating device includes a frame unit including a chair region capable of supporting a user and a leg region extending downward from the chair region, a backrest unit disposed at a rear side of the frame unit, and a handle unit coupled to a first side of the frame unit, the handle unit including a fixing handle body region having a first side coupled to the frame unit and rotatable relative to the frame unit and a lifting handle body region having a first side coupled to the fixing handle body region and rectilinearly movable relative to the fixing handle body region.

A vehicle seat includes a seat back, a seat base, a base structure that is connected to the seat base, a guide structure, and a primary pivot joint that connects the guide structure to the base structure so that the guide structure is able to rotate with respect to the base structure to change a recline angle of the seat back with respect to the seat base. The vehicle seat also includes a slide structure that is connected to the seat back and has a sliding connection to the guide structure, and a link that connects the seat back to the seat base so that the slide structure slides with respect to the guide structure during rotation of the guide structure with respect to the base structure.

Technologies are described for assemblies to recline a seat. The assemblies may comprise a shaft, a threaded end at a first end of the shaft, a Stroke limiter, a seat back mounting, a mounting fastener, an energy absorber, and at least one locknut. A first end of the Stroke limiter may be attached to a second end of the shaft. The seat back mounting may be attached to a second end of the Stroke limiter and the mounting fastener. The energy absorber may be a kinetic energy absorbing element and the shaft may pass through the energy absorber. The locknut may be configured to secure the shaft of the seat recline assembly to the seat frame mounting with the end of the shaft attached to the Stroke limiter on a first side of the seat frame mounting and the energy absorber on a second side of the seat frame mounting.

The invention relates to a vehicle seat having a seat part and a backrest part, which comprises a lower backrest part and an upper backrest part arranged adjacent thereto in the vertical direction of the vehicle seat, a displacement device being arranged with a first section, which is fixedly connected to the lower backrest part, and with a second section, which is fixedly connected to the upper backrest part, the second section being completely displaceable together with the upper backrest part relative to the lower backrest part by means of a displacement movement directed at least in part in the width direction of the vehicle seat, the first section being arranged completely below the upper backrest part in the vertical direction and forming a guideway for the displacement movement of the second section.

A vehicle seat assembly has a seat base, a seat back rotatably connected to the seat base and movable between an upright position and a folded position. An arm has a first end region connected to the seat base and a second end region defining a cam surface. A follower such as a pin is connected to the seat back and fixed relative thereto. The follower engages the cam surface when the seat back is in the folded position.
