Description

Technical Field

[0001] This utility model relates to the field of seat frame technology, specifically a seat frame with integrated seat belt fixing points. Background Technology

[0002] The seat frame is the core support structure of the seat, directly affecting the seat's strength, durability, and ergonomic performance. It is generally made of metal, which has high strength. In the current technology, the seat belt on the seat is fixed to the frame with bolts, which is inconvenient to install and makes it difficult to replace when the seat belt is damaged, making the installation convenience less than ideal.

[0003] For example, patent publication number CN218431757U describes a light aircraft seat, including a seat cushion and a backrest. The seat cushion is hinged to the backrest via a hinged joint. Multiple first telescopic rods are fixedly connected to the bottom of the seat cushion, and a chassis is fixedly connected to the bottom of each first telescopic rod. The telescopic portion of each first telescopic rod is connected to the seat cushion. In this light aircraft seat, the pilot sits on the seat cushion with their back against the backrest. During takeoff, landing, and turbulence, the pilot experiences pressure, squeezing the seat cushion and causing it to descend. Simultaneously, this pressure compresses the first telescopic rods and a first spring, causing the first telescopic rods to contract while the first spring is compressed. The first telescopic rods also constrain the first spring, which in turn pushes the seat cushion with a reaction force. This, combined with a shock-absorbing mechanism, transforms the downward pressure into a horizontal thrust, reducing resonance and improving pilot safety. However, this seat uses bolts to fix one end of the seatbelt to the frame, making installation inconvenient and difficult to replace if damaged, resulting in less than ideal ease of installation.

The end of the seat belt mounting plate 3 contacts the inclined surface 212 on the locking post 211, and the locking post 211 is pushed down along the inclined surface 212 to compress the first spring 210. After the locking post 211 is fully inserted into the hole on the seat belt mounting plate 3, the first spring 210 releases the pressure and resets the locking post 211, so that the seat belt mounting plate 3 is locked in the slot 213 on the locking post 211, thus completing the installation.

[0026] When removal is required, push the lever 205. The lever 205 rotates, causing the rotating block 206 to rotate. The rotating block 206 rotates, causing the fixed rod 207 to move. The fixed rod 207 moves, causing the connecting rope 208 to move. The connecting rope 208 moves, pulling the locking post 211 to move, separating the locking post 211 from the seat belt mounting plate 3, which can then be removed. This allows for quick installation and removal of the seat belt mounting plate 3, facilitating seat belt replacement without the need for bolts, thus improving installation convenience.
