Description

Technical Field

[0001] The utility model belongs to the technical field of lifeboats, and particularly relates to a seat for a free-fall lifeboat. Background Art

[0002] For a free-fall lifeboat, the seat is installed at the bottom inside the lifeboat with the backrest facing the bow of the lifeboat. When the lifeboat directly falls onto the water surface by gravity, a certain impact force will be generated. Therefore, the seat is placed upside down so that the backrest bears the impact force, thereby improving the safety of the lifeboat.

[0003] However, the impact force received by the backrest will be transmitted to the hull. When the number of seats is large, the seat of the lifeboat needs to bear a large impact force. Therefore, designing a seat with high stability and high strength is a problem that needs to be solved by the staff in this field. Summary of the Utility Model

[0011] Further, a plurality of groups of fastening grooves are linearly formed on the step surface. The cross-section of the fastening groove is a convex structure and is parallel to the width direction of the step surface. A plurality of flared grooves are provided at the top of the fastening groove.

[0012] Further, fastening edges that are in clearance fit with the fastening grooves are fixed to both the front side and the rear side of the bottom of the U-shaped seat board. The fastening edges on the U-shaped seat board penetrate through the flared grooves and are arranged in clearance at positions of the fastening grooves away from the flared grooves.

[0013] Further, threaded ports are provided at positions on the bottom surface of the fastening groove that are opposite to the positions of the flared grooves. A plurality of mounting ports are provided at the bottom of the U-shaped seat board. The U-shaped seat board is fixed to the step surface through the mounting ports, the threaded ports, and fasteners.

[0014] Further, a plurality of seat mounting ports and a plurality of relief openings are provided on both the seat board and the footrest. The plurality of relief openings are respectively opposite to the positions of the plurality of mounting ports.

[0015] Further, a plurality of rib plates are linearly arranged among the U-shaped seat board, the seat board, the footrest, the diagonal bracing edge, and the connecting part. The plurality of rib plates are misaligned with the plurality of flared grooves and the seat mounting ports.

[0016] The utility model has the following beneficial effects:

[0017] 1. By designing a stepped boat seat, the utility model can install the seats in batches on the step surface, and the reinforcement bases on each step surface are mutually attached. The blocking edges of the steps can stably bear the impact force generated by the reinforcement bases, and the number of each step surface is relatively small, thereby greatly improving the stability of the seats in the boat.
