The invention relates to a headrest, in particular for a vehicle seat, with a head contact part (11), with a support (12) for mounting the headrest (10) on a fixed structure, with at least one parallelogrammatic linkage (23) between the head contact part (11) and the support (12) that carries the head contact part (11) for movement relative to the support (12) between a first position and a second position, wherein the parallelogrammatic linkage (23) comprises at least two links (16, 17), and each link (16, 17) forms at least one pivot joint (G1A, G2A, G1C, G2C) with the support (12) and at least one pivot joint (G1B, G2B, G1D, G2D) with the head contact part (11), with a latch (19), with a first latch formation on the support (12) and a second latch formation on the head contact part (11), wherein the first latch formation and the second latch formation are in engagement in a locked position and are disengaged in a release position. The special feature is that the first latch formation is fixed on the support (12) or that an upper region of at least one link (116) is provided with the first latch formation, and that the second latch formation is fixed on the head contact part (11).

A juvenile vehicle seat includes a seat bottom and a seat back comprising a backrest and an adjustable headrest. The juvenile vehicle seat also includes a mount for the adjustable headrest. The mount is coupled to the backrest to support the adjustable headrest for movement relative to the backrest.

The present invention relates to a headrest moving device, more particularly, relates to a headrest moving device provided with a contact assisting member for closely contacting two members engaged with each other for moving the headrest so that power can be smoothly transmitted, the noise can be reduced during the movement on the headrest.

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 present disclosure relates to an apparatus for adjusting a headrest wing, and more particularly, to an apparatus for adjusting a headrest wing in which a wire is used to make operating forces at the time of pushing and pulling a headrest wing to be different so that convenience is given to a user.

A head restraint for a seat being adjustable in a vertical direction, and angularly adjustable with regard to lateral portions of the head restraint. A mechanism providing this adjustability is a linear and rotational locking mechanism with a shaft and a slide. The slide is selectively slidably and rotatably mounted on the shaft. The slide has a locked state which linearly and rotationally fixes the slide on, and with respect to, the shaft. The slide has a release state where the slide is linearly and rotatably movable on the shaft. The slide is fixable in a plurality of linear and rotational positions on the shaft in the locked state. The number of linear and rotational positions on the shaft is considered infinite since for all practical purposes, the slide is not restricted to individual discrete positions, but is continuously adjustable to practically any linear and rotational position.

A method for adjusting a vehicle seat includes moving each of a set of first valves respectively associated with ones of a group of first bladders into an open position allowing the receipt of air into and fluidic communication among the group of first bladders, inflating the first group of bladders to a predetermined pressure, and closing each of the set of first valves to maintain an inflation level of each of the first bladders.
