The invention discloses an automotive seat slide rail. The automotive seat slide rail comprises an upper slide rail body, a lower slide rail body, a spring component, a locking component and an unlocking component, wherein the unlocking component drives the locking component to move up and down to achieve locking and unlocking of the upper slide rail body and the lower slide rail body, the locking component comprises a locking sheet and a guide pin, locking tooth parts are arranged on the two sides of the locking sheet, the lower end of the guide pin is connected with the locking sheet in an anchoring mode, and the upper portion of the guide pin penetrates through a guide pin hole in the upper wall of the upper slide rail body; the spring component acts on the space between the locking sheet and the upper wall of the upper slide rail body or the space between the locking sheet and the lower wall of the lower slide rail body; when the upper slide rail body and the lower slide rail body are in a locked state, the locking tooth parts penetrate through an upper tooth window on the upper slide rail body and a lower tooth window on the lower slide rail body; when the upper slide rail body and the lower slide rail body are in an unlocked state, the locking tooth parts disengage from the lower tooth window on the lower slide rail body. According to the automotive seat slide rail, structure becomes simpler, assembly becomes easily, quality control is facilitated, cost is reduced, the weight of the whole slide rail is reduced, and the stress on the spring component from the slide rail in long-time use is effectively eliminated.
