Zero-gravity seat and automobile comprising same

Abstract

The invention discloses a zero-gravity seat and an automobile comprising the zero-gravity seat. The zero-gravity seat comprises a seat, a seat back, a front support and a rear support, the upper endsof the front support and the rear support are hinged to the front end and the rear end of the seat correspondingly, the lower ends of the front support and the rear support are hinged to a seat mounting base correspondingly, the lower end of the seat back can rotate around the rear end of the seat, the rotating center of the seat back is located below the upper end face of the seat, the rotating center coincides with the hinge center of the upper end of the rear support, and the upper end of the rear support is fixed on the seat back. According to the zero-gravity seat, when the seat back andthe seat are in linkage rotation together, the lower end of the seat back and the upper end surface of the seat form a small step difference, and even no step difference exists, so that it is ensuredthat the lower end of the seat back can basically not be propped against the back of a passenger, the fit between the back of the passenger and the seat back is improved, and the riding comfort is guaranteed.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a zero-gravity seat and an automobile comprising the same. Background technique [0002] Zero-gravity technology has applications in the furniture and car seating industries. The schematic diagram of the existing zero-gravity car seat is as follows Figure 1-2 As shown, the seat base 1, the front support 3, the rear support 4 and the seat mounting base 5 form a group of four-bar linkages. When the seat back 2 is adjusted by the recliner, the seat back 2 rotates backward while , the recliner drives the rear bracket 4 to rotate through the connecting plate 202 so that the seat 1 also rotates synchronously. Since the rotation center C of the seat back 2 is set above the seat 1, the seat back 2 rotates backwards during the backward rotation of the seat back 2. The lower end of the chair seat 1 and the upper end surface of the seat 1 form a step difference S, and the greater the ...

Problems solved by technology

This just makes the back of the passenger's trunk be pressed by the lower end convex point A of the seat back during the backward rotation process, so that the back cannot fit the seat back 2, which affects the comfort of the ride.
