AI Technical Summary
In the existing technology, the backrest frame and the seat cushion frame of the seat frame are welded together, which makes the weld points easy to deform during a car collision, resulting in high maintenance costs, poor flexibility, and inability to flexibly replace the backrest frame according to user needs or changes in vehicle configuration.
The seat frame features a detachable design. The backrest frame is detachably connected to the seat cushion frame via a connecting unit, and the support base is detachably connected to the vehicle floor via a mounting unit. The detachability is achieved using bolt connections. The support base and mounting unit enhance connection stability through support sleeves and shock-absorbing pads, and the detachable connection is achieved using mechanical and threaded connections, ensuring the stability of the support base and mounting unit.
This technology achieves stable detachable connection between the backrest frame and the seat, improves the product's technical application, enhances its detachability and ease of maintenance, reduces production and maintenance costs, and improves collision safety and maintenance economy.
