Embodiment Construction

[0038] In order to facilitate the understanding of those skilled in the art, the present invention will be further described below in conjunction with the embodiments and accompanying drawings, and the contents mentioned in the embodiments are not intended to limit the present invention.

[0039] refer to Figure 1 to Figure 2 As shown, a dual-adjustment driver's seat of the present invention includes a seat headrest 1, a seat back 3 and a seat cushion 9;

[0040] The seat headrest 1 is fixed on the upper part of the seat back 3 through two support rods 2;

[0041] The inside of the seat back 3 is provided with two pairs of support frames 4, and the stability of the triangle is used to strengthen the stability of the support of the seat back 3. The shape of the seat back 3 is designed according to ergonomics. The front rest surface 8 is an elastic curved contour in the shape of a raised waist of the human body, and the seat back 3 is also provided with a cam 5 having the same...

Abstract

The invention discloses a double-adjustment driving seat and a backrest outline comfort level simulation method thereof. The double-adjustment driving seat comprises a seat headrest, a seat backrest and a seat cushion, and the supporting stability of the seat backrest is improved by utilizing the triangular property. A cam is controlled to vertically move and rotate around a supporting shaft through by adopting an electromagnetic extension mechanism and controlling rotation of the supporting shaft to adjust the elastic arc-shaped outline of the front leaning face of the seat backrest, and meanwhile the dip angle of the seat backrest is adjusted in a gear adjustment way. The man-machine interface design is effectively optimized, the driving fatigue strength is reduced, and the occurrence probability of driving diseases is reduced. The invention provides a backrest outline comfort level simulation method based on the double-adjustment driving seat. finite element analysis is conducted ona constructed human-seat coupling model to obtain equivalent stress envelope and change situation of the human back under different conditions, and accordingly the comfort design of the seat is guided.

Description

technical field [0001] The invention belongs to the technical field of automobile seats, and in particular relates to a double-adjustable driver's seat and a method for simulating the comfort degree of the backrest contour. Background technique [0002] The car seat is the link between the driver and the car body. It is the most typical human-machine interface point with the most frequent contact with people. It must meet the intentional requirements of consumers when buying a car. The car seat is responsible for supporting the sitting posture, fixing the driver, and reducing vibration in the vehicle. The most important factors affecting its comfort are the individual consumer, the design of the seat itself, and the sitting posture. An unreasonable seat system design not only makes the driver feel uncomfortable, but also easily produces fatigue and causes physical lesions. Studies have shown that the pressure distribution of the human-machine interface is a key factor affec...
