Description

Technical Field

[0001] The present invention relates to the technical field of vehicle seats and berths, and in particular to a berth-integrated middle seat for a commercial vehicle. Background Art

[0002] At present, the sales volume of the domestic commercial vehicle market has been growing steadily, and users have been increasingly demanding more comfortable riding space in the cab. Currently, about 30% of heavy truck cabs have a demand for middle seats. The additional middle seat is often limited by the space of the front instrument panel and the rear sleeper toolbox, resulting in a small riding space. The middle seat can only provide riding functions and the function of folding the backrest forward, which makes it less practical. In addition, due to the existence of the middle seat, the toolbox cannot be equipped with functional configurations such as drawers and refrigerators, which affects the heavy truck drivers' needs for life and dining during long-distance driving.

[0021] like Figure 1 、 Figure 2 and Figure 5 As shown, the berth frame is bolted to the vehicle floor (1100). The berth drawer (800) is mounted in the space below the backrest assembly (100) and the seat cushion assembly (200). It is unlocked via a front unlocking mechanism, and the drawer can accommodate functional amenities such as a refrigerator. The backrest assembly (100) consists of a U-shaped backrest frame (130) and a cushioning layer covering the backrest frame's exterior. A locking hook (110) is located in the center of the backrest frame. Backrest frame connecting brackets (120) are located on either side of the backrest frame's lower end. These brackets connect to the seat back mounting brackets (300) and the outer seat mounting brackets (400) via backrest mounting bolt assemblies (500). A locking catch (310) is located in the middle of the center flat rod of the seat cushion. From the flat position of the backrest assembly (100), the hook (110) is tilted forward and rotated 80°, causing the locking hook (110) to engage the locking catch (310), locking the backrest. When the backrest assembly (100) is raised, the occupant can sit normally.

[0022] By unlocking the lock hook 110 and the lock buckle 310, the backrest assembly can be rotated 100 degrees, flipped back 80 degrees and laid flat with the 900-degree sleeper cushion. When the backrest is laid flat, the passenger can lie down and rest.

[0023] like Figure 3 The figure shows a schematic diagram of the coordination of the backrest, seat cushion frame and berth support frame. A rotating seat is installed at each end of the left and right sides of the middle horizontal rod 320. The rotating seat is a U-shaped frame composed of a seat outer mounting bracket 400 and a seat inner mounting bracket 500. The two lower ends of the 130 backrest frame are inserted into the U-shaped frame and are rotatably connected to the U-shaped frame.

[0024] like Figure 4 and Figure 6 As shown, the seat cushion assembly 200 includes a seat cushion mounting bracket 210 and a seat cushion connecting bracket. The seat cushion mounting bracket 210 is connected and fixed to the 700 berth frame through two M6 bolts, and the seat cushion connecting bracket 220 is inserted into the lower end of the backrest mounting bracket 300 to achieve Z-direction fixation.
