The strength characteristics of the car seat are the main factors affecting the safety of the seat. The strength of the car seat is directly related to the safety of the seat and is the primary content of the seat safety design.
When driving a car, the seat is subject to complex loads. The car seat must have sufficient strength to ensure that the person on the seat receives the least damage; the life of the seat should be long enough not to be deformed or damaged prematurely; When subjected to impact loads, the seat should not be damaged or severely deformed. From the form of the load on the seat, the strength of the car seat can be divided into the static strength, impact strength and fatigue strength of the seat.
Seat static strength characteristics directly affect seat safety and ride comfort, which is an important issue in seat design. Under static load, the seat cushion has little effect on the strength characteristics, so the static strength characteristics of the seat are mainly for the seat frame.
