Problems solved by technology
[0007] The purpose of the present invention is to solve the problems in the prior art that the seat pan is not rigid enough to achieve a good anti-submergence effect, the anti-submarine cost of the air bag is high, and cannot be reused, and to provide a low-cost, reusable , can be widely used in passenger seats and can automatically provide protection for occupants in the event of car collisions and emergency braking, greatly reducing the damage of occupants. A new seat anti-submersion mechanism

Embodiment 1
[0019] exist figure 1 In the shown embodiment, a novel seat anti-submersion mechanism includes a seat frame 1, a seat cushion 2, a seat cushion support 3 and a drive shaft, the seat cushion support 3 is fixed on the seat framework 1, and the seat Cushion support 3 comprises left and right two support plates, and the support plate of seat cushion support 3 is provided with front and rear two tracks, the track rear end center of front track 5 and rear track 6 rear end centers are located between the straight line and the horizontal line. The included angle A is 8°, the center of the rear end of the front track 5 is set obliquely forward and upward in the clockwise direction; The included angle B between the center of the center of the body and the center of the front end of the rear track 6 and the horizontal line is 25°. The seat cushion 2 is slidably connected to the front and rear tracks through two drive shafts. The drive shafts include the main drive shaft 4 and the seconda...

The invention discloses a novel seat descending-prevention mechanism which comprises a seat skeleton, a seat cushion, a seat cushion support and a drive shaft, wherein the seat cushion support is arranged on the seat skeleton and is provided with a track, the seat cushion is connected with the track in a sliding manner through a drive shaft, the drive shaft is connected with a drive mechanism, the drive mechanism is connected with a control system, the drive shaft comprises a master drive shaft and a slave drive shaft, the track is in an arc structure, the track and the master drive shaft and the slave drive shaft are cooperatively provided with a front track and a rear track, the front track takes the center of the rear end part as a rotating center and slants clockwise towards the forward upper part, and the rear track takes the center of the rear end part as a rotating center and slants anticlockwise towards the backward lower part. The seat descending-prevention mechanism is low in cost, can be repeatedly used, and is widely applied to passenger seats. The center of gravity of a passenger does not descend or uplift during the collision, so that the passenger can be protected.
Description
technical field [0001] The invention relates to the technical field of car seats, in particular to a novel seat anti-submersion mechanism. Background technique [0002] The main function of the car seat is to support the weight of the occupant, ease the vibration and impact transmitted from the vehicle body, and provide the occupant with a comfortable and safe riding environment. In the seat system, comfort is the first rigid index that the seat must guarantee. In order to ensure the comfort of the occupants, the angle between the seat cushion and the ground where the car seat is installed is not large, generally not more than 4-8°. When the car has an emergency brake or a frontal collision, the occupant will slide down the seat , so that the waist safety belt is moved above the ribs (the so-called "diving" phenomenon), which will greatly increase the occupant's injury value. [0003] Car seats currently on the market mainly realize the anti-submersion function through the...
