Vertical crash safety driving seat

Abstract

The invention relates to a vertical crash safety driving seat which comprises a seat cushion framework, a backrest framework and a connecting assembly connected between the seat cushion framework and the backrest framework. A backrest inclination rotation shaft transversely penetrates through the connecting assembly. The backrest framework is in rotary connection with the connecting assembly through the backrest inclination rotation shaft and motor drive. An anti-crash supporting screw vertically penetrates through the lower portion of the connecting assembly and penetrates into the seat cushion framework. The seat cushion framework is connected with the connecting assembly through an anti-crash supporting rod screw. The anti-crash supporting rod screw comprises a screw portion located in the connecting assembly and a connecting port penetrating into the seat cushion framework. An inner thread cavity matched with a thread of the screw portion is formed in the connecting assembly. Balls are embedded between the screw portion and the thread matched with the inner thread cavity to form a ball screw structure. A ball guiding tube is further arranged outside the connecting assembly, and the ball guiding tube is provided with a crash normally-closed switch sensor.

Description

technical field [0001] The invention relates to a vertical collision safety driving seat, which belongs to the technical field of automobile passive safety. Background technique [0002] The so-called car seat refers to the main driver's seat and the co-driver's seat of the car; according to the parts, it can be roughly divided into: headrest, backrest, cushion and / or armrest; my country's auto industry has developed rapidly in recent years. The period will continue to develop steadily, and there is a large demand for seats, so the passenger car seat industry still has huge room for development in the future. [0003] The car may be damaged in various ways during driving. Since the human body sits directly on the car seat, the protection of the seat is very important to the human body. The protection of the human body under the huge pressure on the top of the car is not considered, especially now that there are many large trucks, muck trucks, and cement trucks, passenger car...

Problems solved by technology

[0003]The car may be damaged in various ways during driving. Since the human body sits directly on the car seat, the protection of the seat is very important to the human body. Currently, the car The seat only pays attention to the protection of the human body from front-to-back collisions or left-right collisions, but does not consider the protection of the human body under the huge pressure on the top of the car, especially when there are many large trucks, muck trucks, and cement trucks. Casualties caused by being crushed by overturned carts happen from time to time, which urgently need to be resolved; in addition, falling rocks and falling trees also occasionally hit small cars. etc., the space in front of the driver is small, and there is no high-strength support structure in front of the seat, the human head is directly exposed to danger, which is likely to cause casualties
