The invention discloses a seat assembly, an electric sliding rail and a lower rail assembly, the seat assembly comprises a lower rail and a buffer rack, and the top wall of the lower rail comprises a top edge extending towards the center of the lower rail assembly and a flanging extending downwards from the top edge; a plurality of transmission teeth are arranged on the turned-over edge in the length direction; the upper surface of the buffer rack is connected to the top edge through a positioning column; one of the side surface of the buffer rack and the side surface of the flange is provided with a convex part, and the other one is provided with a concave part clamped and matched with the convex part. The upper surface of the buffer rack is connected with the top edge through the positioning column, the side face of the buffer rack is clamped and matched with the concave portion through the protruding portion, the upper surface of the buffer rack forms a fixing face, the side face of the buffer rack forms another fixing face, the fixing faces of the buffer rack are increased, and the connecting strength of the buffer rack and the lower rail assembly is improved. Therefore, the stability of the lower rail assembly is improved. Even if transmission is carried out under large torque, due to the fact that the connection strength is increased, the positions of the buffer teeth are not prone to deviation.
本申请公开了一种座椅总成、电动滑轨及下轨组件,本方案包括下轨和缓冲齿条,下轨的顶壁包括向下轨组件的中心处延伸的顶边和自顶边向下延伸的翻边;翻边沿长度方向布置有多个传动齿;缓冲齿条的上表面通过定位柱连接于顶边;缓冲齿条的侧面,以及翻边的侧面二者之一设置有凸起部,另一者设置有与凸起部卡接配合的凹陷部。缓冲齿条的上表面通过定位柱与顶边连接,侧面通过凸起部和凹陷部卡接配合,缓冲齿条的上表面形成一个固定面,缓冲齿条的侧面形成另一个固定面,增加了缓冲齿条的固定面,提高了缓冲齿条与下轨组件的连接强度,从而提高了下轨组件的稳定性。即便在大扭矩下传动,由于连接强度增加,缓冲齿的位置也不易发生偏移。
