Embodiment Construction
[0021] The present invention will be further described below in conjunction with accompanying drawings and examples.
[0022] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further elaborated below in conjunction with the accompanying drawings.
[0023] Design of the seat basin: the seat basin of plan one is similar to the ordinary seat pot, only the inclination angle of the rear end is adjusted, which reduces the inclination angle and increases the comfort of the seat; plan two bends the two sides of the front end of the seat pot as the seat The side plate 4 in the connection mechanism between the basin and the seat wall plate, and the part used for riveting is removed.
[0024] Compared with the seat pan of an ordinary anti-submarine seat, the rear end of the seat pan of the present invention reduces the inclination angle of the slope 3, which ensures the comfort o...

The invention relates to the technical field of a car seat, in particular to a car seat anti-submarining protection system based on a movable seat basin. The car seat anti-submarining protection system comprises the seat basin, car seat left and right wall plates and a connection mechanism between the car seat left and right wall plates. The car seat anti-submarining protection system is characterized in that side plates (4) on the seat basin are connected with the seat wall plates (14) by a pin shaft (15); an arc-shaped limiting groove (8) is formed in each seat wall plate (14); a certain amount of bosses as energy absorption structures are arranged on the two sides in each limiting groove (8); a limiting pin (9) corresponding to each limiting groove (8) in each seat wall plate (14) is arranged on each side plate (4); a lug (7) capable of being hooked with the free end of a torsion spring (6) is arranged on each wall plate (14); a rotary shaft of each torsion spring (6) is coincided with the pin shaft (15); and the other end of each torsion spring (6) is hooked onto each limiting pin (9). According to the car seat anti-submarining protection system, the anti-submarining performance of a seat is greatly improved, the subsidence structure of a general seat is adjusted, and the car seat anti-submarining protection system is simple in structure, lower in cost, good in portability and convenient for large-scale popularization.
Description
technical field [0001] The invention relates to the technical field of car seat safety, in particular to a car seat anti-submarining protection system (Anti-Submarining Protection System) based on a movable seat pan. Background technique [0002] At present, there are few car seats with ASPS, and the domestic car seats only change the seat frame structure to form a slope with a certain angle, so as to prevent sneaking to a certain extent. Its specific structure is that a 30°-45° slope is set at the front end of the seat, and after the foam skin is packed, an inclination angle of about 20° is formed at the seat basin. An occupant sits in the seat, causing the rear of the seat to sag. In the event of a frontal collision, the human body will have a tendency to slide, and this inclination will give people an oblique rear reaction force, thereby preventing the human body from sliding. However, practice has shown that the anti-submarine slipping effect of this structure is limit...
