Description

Vehicle seat structures and vehicles

Technical field

The present invention relates to the field of vehicle safety technology, and in particular to a vehicle seat structure and a vehicle.

Background technique

In the seat configuration of most existing cars, the seats are mostly arranged in the forward direction of the car, and the seats are equipped with occupant restraint devices such as seat belts and airbags. Taking the frontal collision process as an example, the occupant's torso moves forward relative to the car due to inertia in the initial stage of the collision. However, due to the restraint of the shoulder and chest by the seat belt, the upper torso of the occupant will receive a backward force. After the airbag is deployed, due to the deformation of the airbag, the chest and head of the occupant will be subject to another decelerating force. As a result, the upper torso of the occupant is controlled to avoid damage caused by collision with hard parts of the interior (secondary collision).

At present, the upper anchor point of the seat belt of most passenger cars is fixed on the B-pillar of the car, and the airbag is mostly located in the mechanism in front of the passenger. The shoulder belt part of the safety belt should be in contact with the stronger part of the occupant's shoulder under standard conditions. However, when passengers of different sizes adjust the seat, the relative position of the upper anchor point of the safety belt and the seat will change, and the shoulder belt often Non-standard contact with the occupants. In highly autonomous vehicles, the position and orientation of the occupants can be freely adjusted. Fixing the upper anchor point of the seat belt to the B-pillar of the vehicle obviously cannot obtain ideal constraints in any position and orientation. One solution is to The upper anchor point of the seat belt is fixed at the shoulder of the seat. When the occupant adjusts the seat, the relative position of the upper anchor point of the seat belt and the seat changes little. The seat belt can more ideally restrain the movement of the occupant's upper torso. . At the same time, the seat belt integrated into the seat can also better reduce the impact damage caused by the rebound of the seat belt after the seat belt is loose during a rear collision.

If a seat belt with an upper anchor point set on the upper part of the seat back is used, during a collision, the reaction force restraining the occupant's movement will no longer be transmitted to the stiffer B-pillar, but will be applied to the seat back and seat back. On the angle adjuster connected to the bottom, such a cantilever beam-type force-bearing structure causes the chair back and the angle adjuster to bear greater moments and requires higher stiffness, which in turn leads to an increase in the cost and weight of the seat. Therefore It is common in luxury models and is not easy to use in some small or low-cost models.
