Embodiment
[0019] Embodiment: a kind of car seat energy-absorbing structure, as figure 1 , figure 2 , image 3 shown. Both sides of the bottom end of the seat back 1 are respectively connected to the rear end of the seat cushion 2 through the connecting plate 3, the connecting plate 3 is a circular plate, the seat back 1 is hinged at the center of the connecting plate 3, and the seat back 1 can be wound around The axis of the connecting plate 3 adjusts the pitch angle. The lower side of the connecting plate 3 has a front mounting foot 31 and a rear mounting foot 32, the connection line of the two mounting feet is perpendicular to the working surface of the seat back 1, the front mounting foot 31 is hinged with the seat cushion 2 through rivets, and the rear mounting foot 32 It is connected with the seat cushion 2 through the buffer energy-absorbing device 4 . The structure of buffer energy absorbing device 4 is as figure 2 As shown, it includes a C-shaped buffer plate 41 and a lim...

The invention relates to a connection structure of an automobile seat, in particular to a power-absorbing structure of the automobile seat, which can deform in the collision process. The power-absorbing structure solves the problem that the necks of passengers in rear-end vehicles are easy to sprain during rear-end collision. The power-absorbing structure comprises a seat harness and a seat cushion, wherein the bottom ends at both sides of the seat harness are respectively installed at the rear ends of both sides of the seat cushion through a connecting board. The power-absorbing structure ischaracterized in that the lower side of the connecting board is provided with a front installing pin and a back installing pin, wherein the front installing pin is hinged on the seat cushion, and theback installing pin is installed on the seat cushion through a buffer power-absorbing device. When the rear-end collisions happens, the power-absorbing structure can deform to absorb power through the buffer power-absorbing device so as to protect the safety of the passengers and avoid spraining the necks of the passengers.
Description
technical field [0001] The invention relates to a car seat connection structure, in particular to a deformable car seat energy-absorbing structure during collision. technical background [0002] The safety of passenger vehicles has attracted more and more attention from designers and users. my country also has a complete crash star rating system and strong inspection regulations. When the rear of the car is hit by a rear-end collision, since the seat cannot move, the back of the occupant is close to the back of the seat, and the pressure on the back of the seat is more than 5 times that of the normal situation, and the support point of the head is small. Inertial leaning back can easily sprain the neck. Therefore, a car seat needs a cushioning energy-absorbing structure to reduce the instantaneous impact on the occupant during a rear-end collision and protect the occupant. [0003] The Chinese Patent Office announced the CN201410899Y patent on February 24, 2010, which is c...
