Abstract
Abstract A reclining device mounting structure in an automotive seat, in which a lower bracket of the reclining device is mounted on an upper rail of a sliderail adapted for fore-and-aft adjustment of the seat. More particularly, disclosed is this kind of structure in which the lower bracket of the reclining device is mounted on an mounting portion in the rearward region of an upwardly raised portion formed in the upper rail. The mounting portion is therefore located above the lower rail of the slide rail and in the rearward portion of a seat back of the seat, thus making it easier the mounting of the reclining device on the upper rail.
