Description

Technical Field

[0001] This utility model relates to the field of automotive seat technology, and in particular to a foldable automotive seat frame. Background Technology

[0002] As car usage frequency increases, the demand for car interior functions becomes more diverse, and the functional requirements for cars become higher. Foldable car seats can generally be folded down by reclining the backrest and flipping the entire seat into a folded state. Nowadays, most hatchbacks, MPVs, and SUVs have rear seat folding functions, which is a very practical feature. When we need more loading space, we can expand the loading space simply by folding or folding the seats.

[0003] Existing car seat folding methods are relatively simple, usually only allowing the backrest to fold towards the seat cushion, and cannot be adjusted according to the user's actual needs, thus reducing the practicality of the car seat and consequently reducing the user experience. Utility Model Content

[0004] The purpose of this invention is to provide a foldable car seat frame, which aims to solve the problem of the limited folding methods of existing car seats.

[0005] To achieve the above objectives, this utility model provides a foldable car seat frame, including a base, a seat cushion frame, a backrest frame, a pull member, a locking member, and a backrest lock.

[0006] The seat cushion frame is mounted on the base, the backrest frame is mounted on the base, the pull member is mounted on one side of the base, the locking member is mounted on one side of the base and connected to the pull member and the seat cushion frame, and the backrest lock is mounted on the backrest frame.

[0007] The base includes two side plates and a support rod. The two side plates are respectively connected to the backrest frame and the seat cushion frame. The support rod is fixedly connected to the two side plates and is located between the two side plates.

[0008] The pulling component includes an unlocking plate and a pull strap. The unlocking plate is rotatably connected to the side plate and located on one side of the side plate. The pull strap is fixedly connected to the unlocking plate and located on one side of the unlocking plate.

[0009] The locking component includes a limiting plate, a rotating plate, and a fixing plate. The rotating plate has a limiting groove and a locking protrusion. The fixing plate has a first mating groove and a second mating groove. The limiting plate is fixedly connected to the unlocking plate and is located on one side of the unlocking plate. The rotating plate is rotatably connected to the side plate and is located on the side of the side plate near the limiting plate. The fixing plate is rotatably connected to the side plate and fixedly connected to the seat cushion frame and is located on the side of the side plate near the rotating plate.

[0010] The locking component further includes a return spring, which is installed between the side plate and the limiting piece.

[0011] This utility model discloses a foldable car seat frame. The base provides installation conditions for the seat cushion frame, the backrest frame, the pull member, and the locking member. When the backrest needs to be folded, pulling the backrest lock releases the restriction on the backrest frame, allowing the backrest frame to be folded towards the side closer to the seat cushion frame. When the seat cushion frame needs to be folded, pulling the pull member causes the locking member to rotate, releasing the restriction on the seat cushion frame. At this time, the seat cushion frame can be folded towards the side closer to the backrest frame, thus solving the problem of the limited folding methods in existing car seats.

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0019] Please see Figures 1-4 This utility model provides a foldable car seat frame, including a base, a seat cushion frame 1, a backrest frame 2, a pull member, a locking member and a backrest lock 3;

[0020] The seat cushion frame 1 is mounted on the base, the backrest frame 2 is mounted on the base, the pull member is mounted on one side of the base, the locking member is mounted on one side of the base and connected to the pull member and the seat cushion frame 1, and the backrest lock 3 is mounted on the backrest frame 2.

[0021] In this embodiment, the base provides installation conditions for the seat cushion frame 1, the backrest frame 2, the pull member, and the locking member. When the backrest needs to be folded, pulling the backrest lock 3 releases the restriction on the backrest frame 2, allowing the backrest frame 2 to be folded towards the side closer to the seat cushion frame 1. When the seat cushion frame 1 needs to be folded, pulling the pull member causes the locking member to rotate, releasing the restriction on the seat cushion frame 1. At this time, the seat cushion frame 1 can be folded towards the side closer to the backrest frame 2, thus solving the problem of the single folding method of existing car seats.

[0022] Furthermore, the base includes two side plates 4 and a support rod 5. The two side plates 4 are respectively connected to the backrest frame 2 and the seat cushion frame 1. The support rod 5 is fixedly connected to the two side plates 4 and is located between the two side plates 4.

[0023] In this embodiment, the two side plates 4 provide installation conditions for the support rod 5, and the support rod 5 can improve the support strength of the two side plates 4.

[0024] Furthermore, the pulling component includes an unlocking piece 6 and a pull strap 7. The unlocking piece 6 is rotatably connected to the side plate 4 and is located on one side of the side plate 4. The pull strap 7 is fixedly connected to the unlocking piece 6 and is located on one side of the unlocking piece 6.

[0025] In this embodiment, pulling the pull strap 7 can cause the unlocking piece 6 to rotate, and the rotation of the unlocking piece 6 can cause the limiting piece 8 to rotate.
