Description

Technical Field

[0001] This invention belongs to the field of child passenger equipment, specifically relating to a waterproof sealing structure for a passenger cabin and a seat. Background Technology

[0002] Child safety seats, high chairs, and outdoor chairs are common child seating options, used in different scenarios to provide children with seating and fulfilling their respective additional functions. For example, child safety seats provide good restraint and impact protection for children in cars, enhancing safety; high chairs are used by children at home for meals, allowing them to eat independently or be fed by parents; and outdoor chairs offer lightweight, foldable or non-foldable seats for children to sit on when outdoors, such as during camping trips.

[0003] For existing child seating equipment, for safety and seating comfort, three-point or five-point harnesses are generally required to secure children to the seat. To install these harnesses, several harnesses need to be installed in the seat compartment. The harnesses are usually secured by threading them through the compartment walls. This creates gaps between the harnesses and the compartment, allowing liquids or solid debris to enter and contaminate the seat during daily use. This increases cleaning effort and can also lead to hygiene problems.

[0004] Therefore, it is necessary to develop new connection structures that can improve the sealing of the connection between the seat belt and the cabin to avoid contamination by liquids or solid debris. Summary of the Invention

[0005] The purpose of this invention is to provide a waterproof sealing structure for a cabin that can prevent liquid or debris contamination during use, a seat having the structure, and a method for waterproof sealing the cabin.

[0006] As a first aspect of the invention, a cabin waterproof sealing structure is provided, comprising a waterproof seal disposed on the cabin for a seatbelt to pass through, the waterproof seal being sealed to the cabin such that liquid or debris spilled by the seatbelt when securing a child will not enter the cabin's internal structure through or along the gap between the seatbelt and the cabin, thereby reducing the possibility of uncleanable contamination during routine use. While immersion intrusion of large amounts of liquid is not mandatory in general embodiments, in preferred embodiments, this is achieved by completely sealing the waterproof seal to the cabin.

[0044] A cabin for a seat, which can be used in seats such as child safety seats and high chairs, the cabin being formed as the base of the seat and connected to or integrally formed with the backrest, thereby forming the aforementioned seat.

[0045] like Figure 1 As shown, the cockpit 100 can be formed by injection molding, foaming or processing to form a base for users such as children to sit on.

[0046] In this embodiment, the cabin 100 can be made using a foaming process, with a leather or imitation leather surface layer bonded to its inner surface, preferably made of materials such as PU or EVA.

[0047] like Figure 1 As shown, a cabin cavity 101 is formed inside the cabin 100, and a cabin bottom surface 102 is formed on the bottom surface of the cabin cavity 101. A protrusion 110 is provided on the front side and middle position of the cabin bottom surface 102, which is convex relative to the cabin bottom surface 102. Cabin bottom surfaces 102 are formed on the left and right sides of the protrusion 110 to allow children's legs to rest on the cabin bottom surface 102 when riding. The cabin bottom surface 102 is either flat or concave to facilitate leg fit and riding comfort.

[0048] In this embodiment, the convex seat 110 is positioned between the child's legs after the child is seated, so that the crotch strap of the five-point harness can be attached thereto, thereby securing the child more safely and properly within the cabin cavity 101.

[0049] To accommodate a five-point seatbelt setup, seatbelt anchor points are provided on the front and sides of the cabin 100 to form a five-point seatbelt structure. For example, a five-point seatbelt assembly may consist of a first back strap, a second back strap, and a crotch strap. The upper end of the first back strap is fixed to the seat back, and the second end is fixed to a seatbelt anchor point on one side of the cabin 100. The second seatbelt has a similar structure, with one end of the crotch strap fixed to the front of the cabin 100. A seatbelt connector is provided on both the first and second back straps, and the two first back straps and the second end of the crotch strap are fixed together. For the five-point seatbelt structure, reference can also be made to existing patents such as CN217455752U, CN208978672U, and CN203681326U.

[0050] For the aforementioned five-point seat belts, since the first back strap, the second back strap, and the crotch strap are all fixed to the cabin 100 at one end or pass through the cabin 100, the connection points are easily contaminated or accumulate dirt when liquids are spilled or debris falls, which is detrimental to the cleanliness of the seat and the user experience.

[0051] like Figure 1 As shown, a first waterproof component 20 and a second waterproof component 30 are respectively provided on the left and right sides of the cockpit 100. The first shoulder strap and the second shoulder strap pass through or are fixed to the first waterproof component 20 and the second waterproof component 30 respectively, so as to seal the connection between the two shoulder straps and the cockpit 100 through the first waterproof component 20 and the second waterproof component 30, so as to prevent liquid or debris from entering the gap at the connection or soaking into the interior of the cockpit 100.
