A headrest assembly includes a headrest bun and first and second side supports coupled to first and second side portions of the headrest bun by first and second hinge assemblies, respectively. The first and second side supports each include respective first and second receiving wells and are operable between retracted and deployed positions relative to the headrest bun. A support member is partially received within the headrest bun and includes first and second locator pins extending outwardly from the first and second side portions of the headrest bun, respectively. The first and second locator pins are received in the first and second receiving wells when the first and second side supports are in the retracted position. The hinge assemblies each include a first pivot axis and a second pivot axis. The side support is rotatable along both the first and second pivot axes relative to the headrest bun.

A seat system for a passenger aircraft includes at least one passenger seat and an adjustable headrest attached to the passenger seat. The adjustable headrest includes a plurality of panels including a center panel and at least two pairs of side panels; a plurality of vertically articulated joints each separating each of the pairs one from another; a sliding mechanism such as a rail to facilitate vertical displacement of the plurality of panels, the sliding mechanism connected to the center panel; and a quick release mechanism to facilitate removal of the plurality of panels from the passenger seat, the quick release mechanism engaged with the sliding mechanism. A seat back tray table may further be attached to the back of the passenger seat. The headrest is vertically adjustable, and configured to curve around a passenger's head to provide comfort and stability.

A seat assembly with an adjustable head restraint assembly capable of being adjusted based on an approximate stature or spatial location of an occupant in the seat assembly. A seat assembly may include a sensor in the seat to detect if an occupant is present. The sensor may include a plurality of bladders and pressure sensors, a radar system, or a neuro-monitoring sensor. The sensor may send a signal to a controller indicating the presence of an occupant. The controller may approximate the size and/or spatial location of the occupant and send an adjustment signal to the head restraint adjustment mechanism to adjust the head restraint assembly to an in-use position. The controller may determine that an occupant is not present and send an adjustment signal to the head restraint adjustment mechanism to adjust the head restraint assembly to a non-use position.

An ergonomic chair with an auto-adjusting headrest having a base assembly including floor base, a seat bottom, and vertical structure. A seat back frame and back plate are pivotally attached to the base assembly. An arc-shaped guide bar and head rest restraint are slideably disposed on the back plate. such that the back plate slides approximately parallel to the seat back frame. Arc shaped guide bar rotates as the seat back is tilted rearward and forward.

A headrest assembly includes a front surface and a frame member disposed within an interior of the headrest bun. First and second hinge members are coupled to opposite sides of the frame member and first and second side supports are operably coupled to the first and second hinge members, such that the first and second side supports are independently operable between stowed and extended positions relative to the headrest bun. The first and second side supports extended outwardly from the front surface of the headrest bun in the extended position, and the friction hinges are tuned to move the first and second side supports towards the stowed position when the first and second side supports are contacted by a vehicle occupant during a vehicle impact event.

A thigh support, a seat and a vehicle are provided. The thigh support includes a thigh-support fixing portion, a thigh-support moving portion, a thigh-support driving portion, and a thigh-support bracing portion disposed to the thigh-support fixing portion and located at a rear side of the thigh-support moving portion, in which the rear edge of the thigh-support moving portion is provided with a rear edge recessed portion recessed forwards, a front edge of the thigh-support bracing portion is formed with a front edge protruding portion protruding forwards, and the front edge protruding portion matches the rear edge recessed portion in shape. The seat and the vehicle have the above thigh support.

The present invention relates to a headrest moving device, more particularly, relates to a headrest moving device wherein the user convenience is enhanced since the contact position between the moving unit and the return spring is changed according to the position of the headrest so that the forces being applied by a user are same or similar, that is, there is no significant difference in the operational forces when moving the headrest to either the minimum position or the maximum position thereof.
