A vehicle seat includes a pressure-receiving member disposed rearwardly of an occupant between left and right side frames, and a rocking mechanism configured to cause a left side or a right side of the pressure-receiving member to move frontward and rearward. The rocking mechanism includes a first link member provided pivotally, a second link member provided pivotally on the first link member and pivotally connected to the pressure-receiving member, and an actuator configured to cause the first link member and the second link member to pivot.

Vehicle seat

A headrest is provided including a movable unit that can be shifted to multiple positions in the front-rear direction in a normal mode. A headrest includes first and second headrest pillars, a stationary unit disposed between the first and second headrest pillars, a movable unit movable apart from or close to the stationary unit toward a front or rear direction, an X linkage connecting the stationary unit to the movable unit and including an inside linkage segment and an outside linkage segment rotatably connected each other at a central connecting intersection, and a front-rear locking mechanism including a lock receiver and a locking component engageable with the lock receiver, to lock or unlock the movable unit movable relative to the stationary unit toward the front or rear direction.

Head rest

A headrest includes a right headrest pillar and a left headrest pillar apart from the right headrest pillar, a fixed frame disposed on the headrest pillars, a movable frame coupled to the fixed frame with a movable mechanism, and a front-back locking mechanism locking and unlocking a front-back movement of the movable frame relative to the fixed frame. The movable frame is movable in the front-back direction relative to the fixed frame. The front-back locking mechanism includes a plurality of engaged members disposed outside the right and left headrest pillars in a width direction thereof and a locking member having a plurality of engaging portions to be respectively engaged with the engaged members to lock the movement of the movable frame.

Headrest having engaging members and locking mechanism with engaging portions

A torsion bar configured to assist height adjustment of a seat cushion frame is housed in a hollow coupling pipe positioned between side frames. The inside of the coupling pipe has first and second engagement portions configured to engage and hold one end portion of the torsion bar in an extension direction thereof. The first engagement portion is engaged with a first engaged portion of the one end portion. The second engagement portion is engaged with a second engaged portion of the one end portion in the same position as a position of engagement between the first engagement portion and the first engaged portion in the seat width direction or in a position on the inner side from the position of engagement in the seat width direction, the second engaged portion being positioned closer to one end of a biasing member in the extension direction than the first engaged portion.

The objective of the present invention is to provide a headrest that can have increased comfort and safety. This headrest is provided with: an affixed-side member provided to a headrest pillar; a mobile-side member that is joined to the affixed-side member with a mobile mechanism therebetween and that can move in the front-back direction with respect to the affixed-side member; and a front-back locking mechanism that has an engaged section and a lock member that engages the engaged section, and that locks and unlocks the movement of the mobile-side member in the front-back direction. Also, the mobile-side member has a front-side cover for supporting a head. Furthermore, the engaged section is attached to the back surface of the front-side cover.

Headrest

A headrest is provided that can have increased comfort and safety. The headrest can include: an affixed-side member provided to a headrest pillar; a mobile-side member that is joined to the affixed-side member with a mobile mechanism therebetween and that can move in the front-back direction with respect to the affixed-side member; and a front-back locking mechanism that has an engaged section and a lock member that engages the engaged section, and that locks and unlocks the movement of the mobile-side member in the front-back direction. Also, the mobile-side member has a front-side cover for supporting a head. Furthermore, the engaged section is attached to the back surface of the front-side cover.

A compact headrest having a simplified and more compact mechanism is provided. The headrest includes a first and a second headrest pillars, and a stationary unit disposed therebetween. The stationary unit is movable in a vertical direction along the pillars. The headrest further includes a movable unit movable forward away from the stationary unit and rearward toward the stationary unit through a moving mechanism. The headrest further includes a front-rear locking mechanism having a lock receiver and a locking component engaging therewith. The front-rear locking mechanism locks and unlocks the movable unit moving in a front-rear direction to the stationary unit. The headrest further includes a vertical locking mechanism locking and unlocking the stationary unit stepwise in a vertical direction along the pillars. The headrest further includes an operation unit for simultaneously operating the front-rear locking mechanism and the vertical locking mechanism in a substantially identical direction.

A headrest includes linkage supports with high rigidity. The headrest includes a first headrest pillar and a second headrest pillar, a stationary unit disposed between the first and the second headrest pillars, a movable unit which is movable forward away from the stationary unit and backward toward the stationary unit, and a linkage linking the stationary unit with the movable unit. The linkage includes linkage segments. The stationary unit and the movable unit include supports, respectively. The linkage segments are rotatably connected to and supported by the respective supports. The supports each have a width in the widthwise direction and a thickness in the front-rear direction, the width is greater than the thickness.
