An adjustable headrest for motor vehicle seat. The headrest includes a support structure fixed to a backrest and a body having a front shell and a rear shell. The front shell has a front face intended for contact with the head of a user of the seat, the front face being movable relative to the support structure along a front-rear direction denoted X, over a total travel distance. The total travel distance is formed by a first travel portion provided by a mounting enabling translational movement of the body relative to the support structure while maintaining the position of the front shell relative to the rear shell substantially constant. The total travel distance is also formed by a second travel portion provided by a mounting enabling translational movement of the front shell alone relative to the rear shell.

The invention relates to a spring, in particular to move at least one part of a fixture of the vehicle interior space. It was the object of the invention to create a spring, that does not cause disturbing noises due to vibrations. The object is solved by the spring being made of plastic.

The purpose of the present invention is to provide a headrest to be infallibly locked when returned from a forward tilted position to a using position, without requiring high part accuracy and assembly accuracy. A vehicle seat headrest (4) according to the present invention, having: a stay (402) held on the seat back side; and a headrest main body (4A) supported forward rotatably from a using position with respect to the stay (402), includes: a locking mechanism (500) that fixes a rotation position of the headrest main body (4A) with respect to the stay (402) in the using position; and a stopper mechanism (600) that is not engaged with a regulation part in the using position, but is engaged with the regulation part when the headrest main body (4A) is tilted backward from the using position, to regulate backward tilting of the headrest main body (4A).

A seat headrest comprising: a headrest frame (11) having: a lower frame part (12) configured to be attached to a seat back; an upper frame part (14) pivotally attached to the lower frame part to be moveable between a fully open position and a folded position; a pivot arm (50) connected at a first end (51) to the upper frame part and pivotally connected at a second end (52) to the lower frame part; and a locking mechanism (40) to releasably lock the upper frame part relative to the lower frame part in the fully open position; wherein the locking mechanism comprises a shaft (42) extending through the pivot arm and the lower frame part to define a pivot axis about which the pivot arm pivots relative to the lower frame part, and wherein the locking mechanism further comprises a locking pin (41) configured to extend through the lower frame part, the pivot arm and the upper frame part to lock the pivot arm and upper frame part with respect to the lower frame part when the upper frame part is in a first, fully open, position relative to the lower frame part, and wherein actuation of the locking mechanism by a pushing action of a user causes movement of the locking pin out of engagement with the pivot arm and the upper frame part to permit pivotal movement of the arm relative to the lower frame part about the pivot axis.

The object of the present invention is to provide a headrest capable of, when a user touches the headrest, preventing the user's finger from being inserted into the inner space of the headrest. The vehicle seat headrest according to the present invention includes: a stay (402) held on the seat back side; and a headrest main body (4A) supported forward rotatably from a using position with respect to the stay (402). The headrest main body (4A) has: a main body frame (401) forming a strength member; hinge parts (403a), (403b) which connect the main body frame (401) rotatably with respect to the stay (402); a locking mechanism (500) which fixes the main body frame (401) in the using position with respect to the stay (402); and cushion material (407) which covers the main body frame (401) and the hinge parts (403a), (403b). In the vehicle seat headrest, a resin lower cover (408), having an opening (408a) through which the stay (402) is inserted, covers a lower surface of the headrest main body (4A).

A vehicle head restraint assembly includes a base portion coupleable to a vehicle seat back, the base portion including a cross member portion. Also included is a head restraint operatively coupled to the cross member portion and rotatable about the cross member portion. Further included is a helical drive assembly for translating the head restraint during rotation of the head restraint.

Disclosed is a headrest fore-aft position adjuster including a displaceable body which receives load of an occupant's head and which displaces in a fore-aft direction with respect to a headrest pillar and a lock mechanism which locks and unlocks the displaceable body at a plurality of positions along the fore-aft direction, and the lock mechanism includes an engaging part which displaces in the fore-aft direction integrally with the displaceable body, a plurality of engaged part which is provided along a trajectory of the engaging part and which the engaging part is engaged with in a locked state and the engaging part is configured to engage with the engaged parts from a lateral position.

A headrest includes a headrest body which is tiltably supported by a stay held on a seat back, a lock part which locks the headrest body in a non-tiltable manner, and a lock release part which releases lock of the lock part. The lock release part includes an operation button to be pressed, a biasing member which biases the operation button in an opposite direction to a pressing direction of the operation button, and a bezel which has a cylinder wall and a bottom wall for containing the operation button to be movable back and forth in the pressing direction, and is provided with a locking part which locks the operation button biased by the biasing member to hold the operation button in the cylinder wall. The locking part is provided in the bottom wall.

A head rest that can secure backward view when it is not used, and enable adjustment of its front-and-rear position in use. The head rest is rotatable from a rearmost position to a stored position in which the head rest is tilted down forward. When the head rest is in a use range from the rearmost position to a forward adjustment limit position located in front, the tilting angle of the head rest is adjustable, and the head rest can be rotated forward to the stored position and rotated backward to the rearmost position. By contrast, when the head rest is in the stored position, forward rotation and backward rotation of the head rest are regulated, and the head rest can be rotated backward to the rearmost position.

A seat headrest having a side cushion and a mounting mechanism for use in conjunction with existing, standard airplane seat headrests. The seat headrest has an adjustable side cushion to provide head and neck support by serving as headrests on the side of a user's head. The user may be any individual in a passenger airplane.
