Embodiment Construction
[0010] see figure 1 , the present invention mainly contains left air chamber 3, right air chamber 6, air pressure components and the driving parts installed in left and right air chambers 3,6 to form. The left end surface of the left air chamber 3 is connected to the left end cover 2 by adjusting screws, and the left end cover 2 is provided with a vent hole and a spring ring groove. A piston 10 is installed in the cavity of the left air chamber 3, one end of the piston rod 1 is coaxially connected to the piston 10, and the other end stretches out of the left air chamber 3 and is connected with the seat cushion reclining device. The spring 9 of the cavity of the left air chamber 3 is set on the piston rod 1, the left end of the spring 9 is pressed against the left end cover 2, and nested in the spring ring groove of the left end cover 2, so as to ensure that the position of the spring 9 is relatively fixed, and the spring 9 The right end is pressed against the piston 10 . The...

The invention discloses a pneumatic driving mechanism of a vehicle seat cushion inclination adjusting device. In the pneumatic driving mechanism, the left end surface of a left air chamber is connected with a left end cap, the left end cap is provided with a ventilation hole; the cavity of the left air chamber is provided with a piston; a spring is sleeved on a piston rod, one end of the piston rod is connected with the piston coaxially, the other end extends out of the left air chamber and then is connected with the seat cushion inclination adjusting device; the left air chamber and a right air chamber are respectively communicated with external gas tanks; a normally closed two-position three-way magnetic valve connected with a central processing unit is arranged between the left air chamber and one gas tank, a pressure regulating valve and a normally opened two-position three-way magnetic valve connected with the central processing unit are arranged the right air chamber and the other gas tank; and a single-pole double-throw switch is connected with the normally opened two-position three-way magnetic valve, and the central processing unit and a power supply respectively. By adopting the invention, when the vehicle has a front crash or emergency braking, the piston rod is triggered and launched, thus the seat cushion inclination adjusting device is driven, the cushion inclination is increased, and people in the vehicle are protected; and the pneumatic driving mechanism can be used repeatedly.
Description
technical field [0001] The invention relates to a device for adjusting the inclination angle of the seat cushion of a car safety seat, in particular to a driving mechanism capable of adjusting the inclination angle of the seat cushion during a frontal collision or emergency braking of the car, so as to increase the inclination angle of the seat cushion and protect the interior of the car. crew. Background technique [0002] There is an angle between the seat cushion of the car seat and the ground of the cab. Considering the comfort of the ride, this angle is not large, and the restraint effect on the occupants forward is too small. When the car collides frontally, the forward movement of the occupant is mainly restricted by the safety belt, and the seat cannot restrain the forward movement of the occupant, and cannot provide protection for the frontal collision of the occupant. [0003] The application number is 200510122902.3, and the patent application titled "motor vehic...
