A headrest inclining apparatus for moving a headrest forward by a pressure generated when a passenger moves backward relative to a seat back, in which an energizing device is provided in a support bracket, and the upper part of the support bracket is always energized backward relative to a vehicle. The support bracket is always moved along a fixed path, and is not caught by other parts or devices when moving back into the holder. The support bracket is smoothly and securely returned into the holder.

Headrest inclining apparatus of active head rest

A vehicle seat includes a seat body having a seat back, a pair of left and right legs, a headrest coupled to the seat back at above the seat back through the pair of legs, load detecting means provided on the seat back and having a movable part that displaces in a predetermined direction upon undergoing a load from the front of the seat back; a first interacting member mechanically coupled to one leg of the pair and to the movable part of the load detecting means, to move one leg of the pair in conjunction with a displacement of the movable part caused upon undergoing the load, thereby displacing the headrest frontward, and a second interacting member mechanically coupled to the other leg of the pair and to the first interacting member, to move the other leg of the pair in conjunction with a movement of the first interacting member caused upon moving the one leg of the pair, thereby displacing the headrest frontward.

Vehicle seat

A seat position detecting apparatus includes a fixed rail fixed on a vehicle floor, a movable rail at which a vehicle seat is supported for sliding on the fixed rail, and a position detecting mechanism directly mounted at one of either the fixed rail or the movable rail for detecting a relative position between the fixed rail and the movable rail by detecting the other of either the fixed rail or the movable rail, wherein a first engaging mechanism is provided at either the fixed rail or the movable rail at which the position detecting mechanism is mounted, and a second engaging mechanism provided complementarily to the first engaging mechanism engages with the first engaging mechanism through the position detecting mechanism.

Seat position detecting apparatus, a rail position detecting apparatus and a movable body detecting apparatus

A seat having a collision stopper () activated in a short time period in collision. The seat is constituted of a supporting link (), a stopper link (), a recess/ridge surface (), a stopper (), and urging means (). The supporting link () is installed at its upper portion to the floor side and at its lower portion to the seat cushion side, supporting a seat cushion, and adjusts the height of the seat cushion by inclination in the forward and backward directions in the vertical plane. The stopper link () is attached at its base end section to the floor side such that a rotation end section is rotatable in the forward and backward directions in a vertical plane. The stopper link () has, on its rotation end section side, a projection () projecting sideward. The recess/ridge surface () is provided on the supporting link () side, extending in the direction intersecting the movement path of the projection. When engages with the projection upon receiving a collision load in an assumed direction, the recess/ridge surface () inhibits further rotation of the supporting link () by cooperating with the projection. The stopper () comes in contact with the projection at a position where the projection does not engages the recess/ridge surface (), inhibiting the projection from further separating from the recess/ridge surface (). The urging means () urges the stopper link () in the direction where the projection is in contact with the stopper.

Seat

Head restraint supporting structure of the present invention is such that a head restraint bracket supporting a head restraint is secured to a seat back frame, a stay of the head restraint being inserted into the head restraint bracket. Wherein the head restraint bracket is formed into a tubular shape by joining two end portions of a plate material having been bent, and is secured to the front face of the seat back frame so that junction between the two end portions abuts against the seat back frame. A reinforcement structure is formed at the upper end of the junction. This reinforcement structure prevents the upper end of the junction from being opened by a load being applied to the head restraint, thereby allowing the head restraintto restrain reliably the rearward movement of occupant's head and hence to reliably protect the occupant's neck.

Head restraint supporting structure

When a vehicle is rear-ended and a seated user moves rearward in reaction to the rear-end collision, a load movement of a lumbar part of the seated user is sufficiently transmitted from a pressure plate of operating force generating means to an operating force generating mechanism, regardless of an amount of rearward tilting of a seat back. Then, a pressure roller serving as a driven member of the operating force generating mechanism largely deflects and sufficiently pulls inner cables of respective pulling cable devices, thereby smoothly moving both end portions of a headrest frame upward. As a result, the headrest frame is moved upward smoothly and reliably, and a headrest is moved in an upward-forward direction, that is, toward the head of the seated user smoothly and reliably.

A headrest device includes a headrest provided over a seatback of a seat, a sliding means for slidably adjusting the seat in back and forth directions, a position-adjusting means for adjusting position of the headrest, and a connecting mechanism connecting the sliding means and the position-adjusting means. The connecting mechanism operates the position-adjusting means in conjunction with operation of the sliding means. The connecting mechanism moves in a first direction when the sliding means moves forward, and the connecting mechanism moves in a second direction when the sliding means moves backward.

Headrest device

When a vehicle is rear-ended and a seated user moves rearward in reaction to the rear-end collision, a load generated by a rearward movement of a lumbar portion of the seated user is transmitted from a pressure plate of operating force generating means to an operating force generating mechanism. Then, a pressure roller of the operating force generating mechanism deflects and pulls inner cables of pulling cable devices, thereby moving both end portions of a headrest frame upward. As a result, the headrest frame is moved upward along with headrest supporting brackets smoothly and reliably, whereby a headrest attached to the headrest supporting brackets with headrest stays arranged between the headrest and the respective headrest supporting brackets is moved in the upward-forward direction, that is, toward the head of the seated user smoothly and reliably.

A seat structure for a vehicle which is provided with a seat adjusting mechanism includes a dial-type handle projecting from a position on a seat which is in the vicinity of an occupant restraining webbing. The seat adjusting mechanism is actuated to effect adjustment of the seat by turning the handle. A recess is formed in the side of the handle which is closer to the surface of the seat, the recess extending in the circumferential direction of the handle. A cover member is disposed on the seat in opposing relation to the size of the handle which is closer to the surface of the seat, the cover member concealing a mechanism portion of the seat adjusting mechanism. In addition, a projecting wall is provided on the cover member so as to extend into the recess. Accordingly, the webbing is prevented from deeply entering the gap defined between the handle and cover member.
