Description

Technical Field

[0001] This utility model relates to the field of folding structures, and in particular to a foldable bed and chair. Background Technology

[0002] Existing passenger car or coach seats only function as seats; bed functionality requires separate installation, significantly wasting interior space. Alternatively, they often flatten the seat cushion, backrest, and headrest to form a bed. Current seats typically use a fixed base frame and an adjustable seat cushion. The backrest is folded back to flatten the seat, and the seat cushion, along with the flattened backrest (sometimes including the headrest), forms a bed. This design results in an uneven surface, affecting comfort. Understandably, existing folding seats have different comfort requirements in chair and bed configurations, but they often use the same contact surface. The dual-use design (seat and bed) fails to balance seat and bed comfort; current technology struggles to reconcile these two comfort needs.

[0003] Therefore, there is a need to provide a foldable bed chair to solve the above problems. Utility Model Content

[0004] To address the aforementioned technical problems, this application discloses a foldable bed seat that combines the functions of a chair and a bed through a foldable seat structure design, while ensuring the flatness and comfort of the seat when unfolded into a bed.

[0005] The device includes a base and a seat cushion, a backrest, and a rear backrest that are sequentially hinged to the base. The front end of the seat cushion is hinged to the front end of the base at a first hinge point, and the seat cushion can be rotated forward around the first hinge point to a target angle and then fixed. The lower end of the backrest is hinged to the rear end of the base at a second hinge point, and the backrest can be rotated forward around the second hinge point and then laid flat on the base. The lower end of the rear backrest is hinged to the rear end of the base at a third hinge point, and the rear backrest can be rotated backward around the third hinge point to a target angle and then fixed.

[0006] Furthermore, the non-contact side of the seat cushion and the backrest are both planar structures, and the upward-facing side of the backrest is also a planar structure, so that the seat cushion, the backrest, and the backrest can form a flat bed surface after being rotated around each hinge point with the base.

[0007] Furthermore, the front end of the seat cushion is provided with a front stop, and the front end of the base is provided with an abutment part that abuts against the front stop, so that after the seat cushion flips forward around the first hinge point with the base, the abutment part abuts against the seat cushion and cooperates with the hinge end for limiting and fixing.

[0008] Furthermore, a limiting structure is provided at the front end of the seat cushion, and the limiting structure is located at the hinge point between the seat cushion and the base, so that the seat cushion is limited and fixed after being flipped forward around the first hinge point with the base.

[0009] Furthermore, a multi-position adjustment structure is provided at the hinge point between the backrest and the base to adjust different target tilt angles.

[0010] Furthermore, an adjustment handle is provided between the backrest and the base, and an adjustment handle is provided between the rear backrest and the base.

[0011] Furthermore, a first webbing is provided at the rear end of the seat cushion.

[0012] Furthermore, a second webbing is provided at the non-connecting end of the backrest and the base.

[0013] Furthermore, a third webbing is provided at the non-connecting end of the backrest and the base.

[0014] Furthermore, the lower end of the base is provided with a foot bracket, which is a double-leg structure, so that a drawer space is formed between the two legs.

[0015] The foldable bed chair provided in this application has at least the following beneficial effects:

[0016] 1. This application allows for independent adjustment and folding of the seat cushion, backrest, and rear backrest, effectively differentiating the contact surfaces in both the seat and bed positions. This ensures both the folding effect of the seat, increasing interior storage space, and the ergonomic fit of the seat to prevent fatigue, while also maintaining comfort in the bed position, thus enhancing the user experience.

[0024] Please refer to Figure 1-3As shown, a foldable bed and chair includes a base 1 and a seat cushion 11, a backrest 12, and a rear backrest 13, which are sequentially hinged to the base 1. The front end of the seat cushion 11 is hinged to the front end of the base 1 at a first hinge point 111, and the seat cushion 11 can be flipped forward around the first hinge point 111 to a target angle before being fixed. The lower end of the backrest 12 is hinged to the rear end of the base 1 at a second hinge point 121, and the backrest 12 can be flipped forward around the second hinge point 121 and laid flat on the base 1. The lower end of the rear backrest 13 is hinged to the rear end of the base 1 at a third hinge point 131, and the rear backrest 13 can be flipped backward around the third hinge point 131 to a target angle before being fixed. By flipping the seat cushion 11, backrest 12, and rear backrest 13 separately, the contact surfaces when in the seat and bed states can be effectively separated, satisfying the user's comfort in different states. Furthermore, the seat cushion 11, backrest 12, and rear backrest 13 are fixed in the seat state using existing structures, which will not be described further here.

[0025] Based on the above technical solution, the non-human-contact sides of the seat cushion 11 and backrest 12 are both flat, and the upward-facing side of the backrest 13 is also flat. This allows the seat cushion 11, backrest 12, and backrest 13 to form a flat bed surface after being rotated around their respective hinge points with the base 1. This not only increases the interior space and makes the interior more aesthetically pleasing and streamlined, but also enhances the stability of the bed after it is unfolded and the comfort of lying down. It is understandable that... Figure 2 As shown, considering that the backrest length is generally greater than the seat cushion length, the second hinge point 121 is higher than the first hinge point 111. At the same time, the second hinge point 121 is located at the near end rather than the bottom end (farthest end), which allows the backrest to be flipped flat and fill the empty space after the seat cushion is flipped, so as to further form a flatter and seamless bed surface, improving the flatness of the bed surface and the comfort of use.

[0026] The steps for transforming a seat into a bed can be understood as follows: first, flip the seat cushion forward and flatten it (with the back of the seat facing up); then, flip the backrest forward and flatten it (equivalent to filling the area left empty after the seat cushion is flipped); finally, flip the backrest backward and flatten it, thus creating a flat bed surface for resting or freeing up the maximum space for placing items.

[0027] In a preferred embodiment, the front end of the seat cushion 11 is provided with a front stop 112, and the front end of the base 1 is provided with an abutment part 113 that abuts against the front stop 112. This allows the seat cushion 11 to flip forward around the first hinge point 111 with the base 1, and the abutment part 113 abuts against the seat cushion 11 and works with the hinge end for limiting and fixing, making the unfolded structure more stable, increasing the load-bearing capacity of the bed, and enhancing its home comfort.

[0028] It is understood that, preferably, a limiting structure 114 is provided at the front end of the seat cushion 11. The limiting structure 114 is located at the hinge point between the seat cushion 11 and the base 1, so that the seat cushion 11 is limited and fixed after being flipped forward around the first hinge point 111 with the base 1.

[0029] Specifically, a multi-position adjustment structure 132 is provided at the hinge between the backrest 13 and the base 1 to adjust different flipping target angles.

[0030] In an optional embodiment, an adjustment handle (not shown in the figure) is provided between the backrest 12 and the base 1, and an adjustment handle (not shown in the figure) is provided between the rear backrest 13 and the base 1. The adjustment handles facilitate the flipping adjustment and unfolding operation of the backrest 12 and the rear backrest 13. Existing technology can be used for the adjustment handles.

[0031] Optionally, the rear end of the seat cushion 11 is provided with a first webbing 115 to facilitate lifting the seat cushion 11 for flipping.

[0032] In an optional embodiment, a second webbing 122 is provided at the non-connecting end of the backrest 12 and the base 1 to facilitate lifting the backrest 12 for flipping. Specifically, the second webbing 122 may be provided on the side of the backrest 12, and two sets are provided on the two sides to facilitate flipping the backrest 12 from the side.

[0033] Furthermore, a third webbing 133 is provided at the non-connecting end of the backrest 13 and the base 1 to facilitate lifting the backrest 13 for flipping. Specifically, the third webbing 133 can be provided on the side or top of the backrest 13 to facilitate flipping the backrest 13 from the side.

[0034] For easy folding and storage, a leg member 14 is provided at the lower end of the base 1. The leg member has a double-leg structure, which will create a drawer space between the two legs and increase the storage volume.

[0035] The foldable bed chair provided in this application has at least the following beneficial effects:

[0036] 1. This application allows for independent adjustment and folding of the seat cushion, backrest, and rear backrest, effectively differentiating the contact surfaces in both the seat and bed positions. This ensures both the folding effect of the seat, increasing interior storage space, and the ergonomic fit of the seat to prevent fatigue, while also maintaining comfort in the bed position, thus enhancing the user experience.

[0037] 2. By designing the flip-up design, the contact surface is changed from the same surface of the seat and the bed to different surfaces of the seat and the bed. This ensures that the ergonomics of the seat is improved and the seat comfort is enhanced, while meeting the strength requirements of GB15083 M1 class seats. At the same time, the load-bearing strength is increased in the bed state, making it more suitable for home use as a travel car bed seat. It not only optimizes the space shape, but also releases more interior space when the seat cushion is flat.

[0038] The above description is only a preferred embodiment of this application. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of this application, and these improvements and substitutions should also be considered within the scope of protection of this application.
