Seat cushion extension apparatus

Abstract

A seat cushion extension apparatus comprises a slide rail disposed on a lower side of a cushion frame; an extension panel coupled to a front end of the slide rail and disposed on a front side of the cushion frame; an extension motor having a lead screw, disposed on the lower side of the cushion frame; a first hinge bracket coupled to the end of the slide rail and disposed at a rear upper side of the extension panel; and a second hinge bracket coupled to the end of the lead screw and disposed at a rear lower side of the extension panel, wherein the extension panel is configured to slide forward along the slide rail and to extend forward while rotating in a front upper direction through actuation of the lead screw driven by the extension motor.

Description

technical field [0001] The present invention relates to a seat cushion extending device, and more particularly, to a seat cushion extending device capable of guiding a stable sitting posture of a passenger by preventing a slack phenomenon of a seat cushion cover and maintaining an aesthetic appearance, thereby extending the seat cushion. prevent creases at corners. Background technique [0002] Generally, front and rear seats for a driver and a passenger are installed on the floor of the vehicle. [0003] The front seat adopts a split type, that is, the driver's seat and the passenger seat are arranged separately, and the rear seat adopts a bench type, that is, the left and right seats are integrally connected. [0004] In all configurations of front seats for vehicles in the related art, the front seats consist of a seat cushion fixed on a horizontal frame and a seat back fixed on a vertical frame along a rail mounted on the floor Moving forward and backward, the vertical...

AI Technical Summary

Problems solved by technology

[0011] However, in the related art, when the seat cushion is extended, slack occurs at the pad portion and the cover portion, so that the passenger's sitting posture becomes uncomfortable, such as Figure 2A As shown, and with the bending of the corner portion of the seat, curves and wrinkles appear, thereby deteriorating the aesthetics of the appearance, such as Figure 2B shown

[0012] In addition, when the linear movable mechanism 30 extends the seat cushion, the linear movable mechanism may effectively support the passenger's thigh region, but interference occurs at the lower leg so that the leg cannot be bent.
