Description

Technical Field

[0001] This utility model belongs to the field of automotive parts technology, and relates to a headrest installed on a car seat, specifically a novel rear-center folding and locking headrest and a car seat. Background Technology

[0002] Current car rear seats typically have headrests. The headrest located in the middle of the rear seat needs to be foldable. When needed, the headrest can be folded upright, and when not in use, it can be folded back to prevent it from obstructing the rear windshield and affecting the driver's view of the rear. However, due to manufacturing precision issues, traditional folding headrests have a gap between the locking plate and the metal welding plate at the locking position. This causes a slight wobble in the headrest, which vibrates and produces noise when bumps in the road resonate with it. Furthermore, the locking plate driven by the existing folding headrest button assembly is usually a plate structure, which limits the headrest's shape and is not conducive to its design. Summary of the Invention

[0003] In view of the above-mentioned technical problems and shortcomings, the purpose of this utility model is to provide a novel rear-center folding locking headrest, which has the advantages of simple structure, low noise, and unrestricted shape.

The headrest rod welding assembly includes a headrest rod, a crossbar mounted on the headrest rod, and a first welding plate and a second welding plate mounted on the crossbar. The first and second welding plates have locking grooves that engage with the locking plate for locking. The headrest frame has semi-circular mounting grooves on both sides at the locations where the headrest rod welding assembly is installed. The two ends of the crossbar are positioned within these semi-circular mounting grooves and sealed with pressure plates, allowing the headrest frame to fold backward relative to the crossbar. The headrest frame has locking grooves on both sides at the locations where the first welding plate engages with the crossbar. Anti-sway parts are provided at opposite positions. When the headrest frame is upright, the end of the first welding piece is connected to the anti-sway part. Rubber nails are provided on the headrest frame at positions opposite to the second welding piece. When the headrest frame is folded backward, the second welding piece is connected to the rubber nails on the headrest frame. The back shell is installed on the rear side of the headrest frame. The locking piece is located inside the headrest frame and can slide relative to the headrest frame in the Y direction. The compression spring is located between the headrest frame and the locking piece and is used to drive the locking piece to reset, thereby locking. The button assembly is installed on the headrest frame. By pressing the button assembly, the locking piece is driven to move in the Y direction, away from the locking groove, thereby unlocking.
