Abstract: A structure of seat back in vehicle seat, wherein a back board element is provided the said backward side of the seat back in such a manner as to normally provide a substantially flat plane rigid enough to withstand one load applied toward a backward side of the back board element, thereby to allow the back board element to be usable as a means for carrying load and cargo thereon, while being resiliently deformable in a backward direction of the vehicle seat by another load applied toward a seat occupant's back support side of said seat back. A plurality of crevices may be defined properly in one side of the back board element so as to effectively permit the back board element to be either in the substantially flat state or in a resiliently deformable state.

Abstract: A dual reclining device comprising a pair of reclining elements provided on both lateral sides of an automotive seat, with a tubular connecting rod being connected with two shafts respectively of those two reclining elements. The tubular connecting rod has an L-shaped end portion having a longitudinal pressed region and a transverse flange portion, wherein a hole is formed in the transverse flange portion. One of the two reclining element shafts is inserted through such hole of transverse flange portion and welded thereto, while being also welded to the longitudinal pressed region of transverse flange portion. Such easy welding is effective in absorbing both longitudinal and radial errors or non-alignment between the two shafts.

Abstract: A height adjusting device for a vehicle seat, in which are provided a height adjusting mechanism and a seat surface inclination adjusting mechanism. The height adjusting mechanism includes a linkage between a seat frame and base frame, with brackets fixed at the seat frame, whereas the seat surface inclination adjusting mechanism includes a tilt link connected with the linkage and bracket of the height adjusting mechainsm in a manner to be movable independently of the latter. Thus, the seat is adjusted in height and in inclination angle, independently, by operating each of those two mechanisms, without coactive influences therebetween.
