AI Technical Summary
The fixed sleeper space behind the cab of traditional commercial vehicles has low utilization rate. When the seats are laid flat, the height is inconsistent and the stability is poor. It is impossible to quickly adjust the space layout, which affects comfort and safety.
By flattening the seat back to create a uniform height, and combining the design of a mobile sleeper berth with a fixed sleeper berth, a dual fixing mechanism using nylon buckles and hook and loop fasteners is used to achieve flexible conversion and stable fixation between the seat and the sleeper berth.
This design allows the seat to be laid flat at the same height as the sleeper berth, improving lying comfort, ensuring quick space adjustment and safety, while also reducing production costs and meeting diverse usage needs.
