Description

Technical Field

[0001] The utility model belongs to the technical field of vehicle seats, and particularly relates to an anti-submerging structure for a large-angle zero-gravity seat. Background Art

[0002] As a key component of a vehicle and an important part of the restraint system, a vehicle seat should be able to provide strong support for the occupant during a frontal collision, prevent the occupant from moving, reduce the occupant's injury, and have a good protection effect. At the same time, the vehicle seat should also be able to provide good comfort for the occupant and relieve the fatigue of the driver and passengers.

[0003] The key to the anti-submerging installation structure of a vehicle seat lies in designing a support system that can resist forward impact forces. Such a structure usually includes a strengthened seat frame, a specific seat track design, and a fixed point firmly connected to the vehicle floor. During a collision, these designs can prevent the seat from sliding forward, prevent the occupant's body from submerging, reduce the risk of the occupant colliding with the steering wheel or dashboard, and thus improve the safety of the occupant. This technology requires the comprehensive application of materials science, mechanical analysis, and safety testing to ensure that the seat can be stably fixed under various collision conditions and protect the occupant. However, the current anti-submerging designs of vehicle seats are all for normal sitting postures. For large-angle zero-gravity seats, how to reduce the situation where the vehicle seat is adjusted to the zero-gravity posture during driving and then collides, and how to prevent the occupant's body from sinking or leaning forward, so as to improve safety while taking comfort into account. Summary of the Utility Model

[0004] The utility model provides an anti-submerging structure for a large-angle zero-gravity seat, aiming to solve the problems raised in the background art.

[0005] The utility model is realized as follows: an anti-submerging structure for a large-angle zero-gravity seat includes a zero-gravity seat, a concave half-basin, a seat cushion airbag, and a three-point seat belt;

[0006] The zero-gravity seat includes a backrest frame and a seat cushion frame, and the concave half-basin is welded and fixed on the seat cushion frame;

[0007] The seat cushion airbag includes a gas generator and an airbag cloth. The seat cushion airbag is installed in the concave half-basin, and the airbag cloth is laid flat on the concave half-basin;

[0008] The three-point seat belt includes a first buckle, a second buckle, and a retractor. The first buckle and the second buckle are fixed on the seat cushion frame. The seat cushion frame includes a fixed bracket and a reinforced side plate, and the fixed bracket and the reinforced side plate are distributed oppositely. Among them, the first buckle is fixed on the fixed bracket, the second buckle is fixed on the reinforced side plate, and the retractor is fixed on the backrest retractor support sheet metal in the backrest frame.

[0009] Preferably, the zero-gravity seat further includes a seat cover, seat foam, and a leg rest. The backrest frame, seat cushion frame, and leg rest are connected by bolts. The seat foam is filled in the backrest frame and seat cushion frame, and the seat cover wraps the seat foam.

[0010] Preferably, the gas generator is used to generate gas to inflate the seat cushion airbag.

[0011] Preferably, the first buckle includes a detonator, and the detonator is used to detonate the lock head of the first buckle.

[0012] Preferably, the first buckle includes a lock head. After the detonator pulls the lock head, the three-point seat belt is pulled back to achieve the purpose of tightening and restraining the occupant.

[0013] Preferably, the first buckle and the fixed bracket are fixed by bolts and nuts, the second buckle and the reinforced side plate are fixed by bolts and nuts, and the retractor and the backrest retractor support sheet metal are fixed by bolts and nuts.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] There is a collector on the whole vehicle, and the collector collects the vehicle collision signal. When the zero-gravity seat is adjusted to the zero-gravity posture and the vehicle collides, the seat cushion airbag control unit receives the collision signal transmitted by the vehicle collector, and the seat cushion airbag will automatically inflate, raising the occupant to prevent the occupant from diving and reducing the occupant's injury. Specifically, when the vehicle undergoes a frontal collision, the airbag control unit will receive the collision signal transmitted by the vehicle collector. At this time, the airbag control unit drives the gas generator to release gas, and the seat cushion airbag inflates after being filled with gas. The seat cushion airbag expands and raises the occupant to prevent the occupant from diving and reducing the occupant's injury. At the same time, the vehicle collector transmits the collected collision signal to the vehicle domain controller, and the vehicle domain controller controls the detonation of the detonator on the first buckle. After the detonator detonates, the lock head on the first buckle is pulled back. At this time, the three-point seat belt is pulled back a certain distance, so that the three-point seat belt is tightened, further restraining the occupant and reducing the occupant's injury. At the same time, because the airbag is installed in the concave half-basin, it will not affect the riding comfort. The seat used in the present utility model, because its use scenario is different from that of traditional seats, adds a seat cushion airbag and a three-point seat belt to protect the occupant on the zero-gravity seat, realizing the avoidance of the occupant's body sinking or leaning forward during a collision during vehicle driving, ensuring the riding comfort and safety of the occupant.
