摘要： A headrest for vehicle seat includes: a generally inverted-U-shaped frame having a pair of headrest stays defined therein; and an impact absorption bar fixedly connected between those two headrest stays. The impact absorption bar is located in a predetermined spaced relation with an upper horizontal frame portion of the generally inverted-U-shaped frame. When a rear-end collision or the like occurs, a head of seat occupant is stably received by those impact absorption bar and upper horizontal frame portion, while the impact absorption bar being readily deformed by backward excessive great load applied thereto from the seat occupant's head to thereby absorb and reduce a corresponding impact energy to be imparted to the head.

摘要： A seat height adjustment mechanism is provided, which includes a backward link element, a ratchet-type drive mechanism operable by an operating lever to cause vertical movement of the backward link element to adjust height of seat, and a locking mechanism. The backward link element is normally locked by the locking mechanism to reinforce the backward link element itself. When the operating lever is rotated during an idle stroke (S) inherently given in the ratchet-type drive mechanism, the locking mechanism is actuated to unlock the backward link element, thereby allowing the backward link element to be vertically displaceable through operation of the ratchet-type drive mechanism by further rotation of the operating lever.

摘要： An armrest for a vehicle seat, wherein armrest is rotatable between a use position for supporting an arm of an occupant and non-use position where the armrest body stands upright along the vertical direction of the seat back of the seat, under the force of a return spring, and wherein there is arranged a buffer means for reducing a rotation rate at which the armrest is rotated downwardly to the non-use position. Thus, the armrest body may be rotated at a moderate rate towards the non-use position, thereby avoiding a serious collision of the armrest body against a part of the vehicle.

摘要： In a seat back structure, an auxiliary frame having a pressure receiving portion and a headrest mounted thereon is movably provided in seat back frame via guide element and link element. The guide and link elements are respectively disposed in upper and lower portions respectively of the auxiliary and seat back frames. Biasing element is provided to the link element, such that a line of force of the former is positioned on one side of a pivotal point of the link element, thereby retaining the headrest at initial position, and that, when excessive backward load is applied to the pressure receiving portion, the link element is rotated to displace the line of force toward another side of the first pivotal point, whereby the auxiliary frame is displaced forwardly and upwardly of the seat back frame, thereby causing the headrest to move to a postion for supporting a head of seat occupant.

摘要： Impact absorption structure is provided in side frame element of seat cushion frame, wherein the side frame element is basically of a closed cross-section portion therein, including forward and backward support points therein. In the structure, an opened cross-section area is defined in the closed cross-section by forming a cut-away portion in a lower part of a forward local region of such closed cross-section portion between the forward and backward support points, so that the opened cross-section area is deformable at said cut-away portion by a great load transmitted from a seat back frame thereto, thereby absorbing a corresponding impact.

摘要： A headrest for seats for use in vehicles has a fixed frame fixedly secured to the upper ends of stays supported on a seat back, two right and left movable frames secured to a panel of the headrest, and two pairs of parallel links connecting the fixed and movable frames; a first pair connecting the right movable frame to the right end portion of the fixed frame, and a second pair connecting the left movable frame to the left end portion of the fixed frame. One of the first pair of links is connected with one of the second pair via a connecting portion. With such structure, the headrest can be moved back and forth with little change in height, and, since there are no moving parts present in all portions of the headrest except in the two end portions of the fixed frame, a throughbore can be provided in the central portion of the headrest.
