AI Technical Summary
Existing car seat safety devices are inconvenient to remove in emergency situations and offer insufficient protection. In particular, the connection between the headrest and the seat is complex, and the seat belt coverage is limited, making it impossible to effectively secure the passenger's body.
A car seat safety device including a connecting mechanism and a protective mechanism was designed. The connecting mechanism ensures a secure and convenient connection between the headrest and the seat body through a rod, a fixing sleeve, a locking block, a locking groove, a rotating sleeve, a pressure plate, and a quick-release mechanism. The protective mechanism provides all-round restraint through a combination of chest straps, waist straps, hip straps, and a locking plate.
It enables quick disassembly of the headrest and seat body, avoiding wasted time in emergencies and enhancing passenger safety and stability in accidents. In particular, the comfort and elasticity of the cotton and linen straps adapt to different body types, providing all-round protection.
