The chair frame 1 is one of the core components of such a shifter with two state of sitting and lying change, and its design requires balancing the load-bearing capacity, stability, mobility and user requirements to ensure that the full disabled population can obtain a safe, comfortable and functionally rich seating and resting experience.

In particular, in the present embodiment, the support structure of the chair frame 1 is generally frame-shaped, with a stable foundation to ensure that the displacer remains stable in various postures. These support structures should be designed to take into account the weight and body support requirements of the user. The chair frame 1 is typically made of a sturdy and durable material, such as a high strength metal alloy or a sturdy engineering plastic. This ensures that the chair frame 1 has sufficient load-bearing capacity and durability.

It will be appreciated that some chair frame 1 designs allow some or all of the chair frame structure to be disassembled for easier cleaning, maintenance or storage.

In this embodiment, a plurality of road wheels 6, typically four or more, are attached to the bottom of the chair frame 1, and these road wheels 6 are free to rotate to move the chair. The road wheels 6 are generally wear resistant and provide smooth movement without damaging the floor surface.

It will be appreciated that the road wheels 6 of the chair frame 1 should have sufficient mobility so that a user or carer can easily move the chair seat to different positions, including bedrooms, living rooms, bathrooms, etc. In most cases, the road wheels 6 are bidirectional mute wheels, so that the comfort and the overall use experience of the use are further improved.

In the embodiment, the seat 5 realizes the height adjustment of the seat 5 through the controllable air supporting component 14 arranged on the seat frame 1, the seat 5 is provided with the cushion 16, and the riding comfort is improved through the cushion 16. By means of the controllable air support assembly 14, a user or carer is allowed to raise or lower the chair seat 5 as required, so that different people can be satisfied, and meanwhile, the chair seat can be raised or lowered to be flush with a bed, and the transfer of people is facilitated.

In use, a user or caregiver can adjust the gas stay assembly 14 via a control handle or button to effect height adjustment. This design ensures that the user can easily adjust the seat 5 at different heights to meet his or her different seating needs and transfer needs, increasing comfort, providing better support, and also increasing the versatility of the chair.

In this embodiment, the chair frame 1 is also fitted with an adjustable lifting armrest 7 to provide additional support and convenience. Armrests 7 are typically located on either side of the chair seat to provide support for the user in standing and sitting.

In this embodiment, the front portion of the armrest 7 extends beyond a front grip 15, and this front grip 15 is typically located at the front end of the armrest 7 so that a user can conveniently grasp it from the front to effect manipulation of the chair frame 1. The front grip 15 provides additional control convenience, particularly when the user needs to move or adjust the chair position.

In this embodiment, the chair frame 1 is provided with a reversible foot rest 12, which provides additional support and convenience to the user.

In this embodiment, a detachable bedpan 8 may be installed in the chair frame 1, which provides a convenient sanitary facility for the user. This requires that the chair design allow for the storage and use of the bedpan 8.

In this embodiment, the seatback 2 is another important component of the shifter that changes in both sitting and lying states. Its design needs to take into account the comfort, support and adjustability of the user to ensure that the user can switch between sitting and lying states, meeting their different seating and resting needs.

In particular, the back 2 is generally made of a solid internal support structure, fitted with a comfort pad 11, the back 2 being connected to the frame 1 by hinges, so that it can be adjusted between different angles. These hinges generally allow the chair back 2 to rotate about it, allowing the user to easily switch from a sitting to a lying position, or to choose an intermediate position between the two.

It will be appreciated that the internal support structure of the seat back 2 generally comprises a sturdy frame to ensure stability and reliability of the seat back 2. These support structures remain in shape in different states to provide support. It will be appreciated that the cushion layer 11 of the backrest 2 is a combination of high density foam filled and abrasion resistant fabric or leather in order to meet comfort requirements. This ensures that the seat back 2 provides adequate support and comfort.

In this embodiment, the adjusting mechanism 3 of the chair back 2 is responsible for controlling the angle of the chair back 2, specifically, in this embodiment, the adjusting mechanism 3 is a controllable air stay rod symmetrically installed and two ends of which are respectively hinged on the chair frame 1 and the chair back 2, which can enable a user or a carer to easily adjust the position of the chair back 2 so as to meet the requirements of the user. Such an adjusting mechanism 3 controls the angle of the seatback 2 by changing the supporting force of the gas stay. The advantage of this mechanism is that it provides a smooth, accurate adjustment, which the user can fine tune to his own needs.

It should be noted that the chair back 2 is typically provided with one or more rear grips 9, and the user may control the walking of the chair frame 1 through the rear grips 9. In addition, a control handle 10 can be arranged on the rear grip 9, and a user can operate the adjusting mechanism 3 of the chair back through the control handle 10 to realize sitting and lying changes.

In this embodiment, in order to ensure structural stability in the lying state, the foldable support 4 is an important component of a shifter for changing between the sitting and lying states, and is used to support the change of the seat back 2 in different states, so that the user can easily switch between the sitting and lying states. The design of the foldable support 4 generally allows for comfort and support requirements for the user to ensure that the chair back provides stable support when lying down and does not interfere with the user when sitting down.

In this embodiment, the foldable support 4 is typically made of a strong material, such as a metal alloy or a high strength plastic. This ensures that the support has sufficient strength and stability to bear the weight of the user and provide stable support. The foldable support 4 is connected to the chair back 2 by a hinge enabling it to fold and unfold freely between different angles. This hinge design allows the user or caregiver to unfold the collapsible support 4 to support the chair back, or fold for more space or portability, if desired.

It will be appreciated that in order to provide additional stability, some collapsible supports 4 may be provided with a locking mechanism that allows a user to lock the collapsible support at a desired angle to prevent accidental collapse or deployment.

In this embodiment, in order to ensure the mobility of the shifter, the movable end of the foldable support 4 is provided with a guide wheel 13, and the guide wheel 13 and the moving wheel 6 together realize the shifting and walking requirements when the shifter is in a lying state.
