[0024] Example 1:

[0025] In this embodiment, a chair with a stretcher function, such as Figure 1 As shown, it includes a seat base 1 and a stretcher body arranged on the above-mentioned seat base 1. Specifically, the above-mentioned seat base 1 is fixed on the floor of the ambulance compartment, and the surrounding space is wider. The above-mentioned stretcher body includes a seat plate 2, a leg bracket 3, a backrest 4 and a seat adjuster 5 for adjusting and locking the angle between the seat plate 2 and the backrest 4. The above-mentioned seat plate 2 is detachably mounted on the above-mentioned seat base 1. After removing the above-mentioned seat plate 2, the above-mentioned stretcher body can be separated from the above-mentioned seat base 1. The above-mentioned backrest 4 is rotatably connected to the rear end of the above-mentioned seat plate 2 through the seat adjuster 5, and the above-mentioned leg bracket 3 is telescopically connected to the above-mentioned seat plate 2.

[0026] With this structure, when a stretcher is needed to transport a patient, the leg support 3 is pulled out and the backrest 4 is flattened through the seat angle adjuster 5, and then the seat plate 2 is removed from the seat base 1, and it can be used as a stretcher to transfer the patient. At this time, one person lifts the leg support 3 in the front, and the other person lifts the backrest 4 in the back. The patient lies on the seat plate 2 and the backrest 4, and both legs are supported by the leg support 3. When the patient arrives in the car and needs to rest in a sitting position, the seat plate 2 is re-fixed to the seat base 1, and the leg support 3 is retracted into the seat plate 2, and then the backrest 4 is adjusted to a suitable angle. The patient can sit or lie on the seat with a stretcher function. It is easy to operate, flexible to disassemble and assemble, and convenient to maintain, so that the vehicle seat has the function of detaching a stretcher to transfer patients.

[0027] It is worth noting that the above-mentioned seat recliner 5 is an existing technology. It is a device installed on the car seat to achieve angle adjustment of the seat back 4. Therefore, its structure will not be repeated. It is divided into a step-by-step adjustment recliner and a stepless adjustment recliner. The above-mentioned seat recliner 5 is preferably a step-by-step adjustment recliner. The locking or unlocking of the device is controlled by a handle or rod to achieve discontinuous adjustment of the angle of the car seat back 4, and the relative position of the above-mentioned backrest 4 and the seat plate 2 can be locked.

[0028] As a specific implementation of this embodiment, the above-mentioned seat plate 2 includes a cushion 6 and a frame 7. The above-mentioned cushion 6 is laid on the above-mentioned frame 7. The interior of the above-mentioned frame 7 is hollow and has a frame and internal vertical and horizontal supports. Two limit seats 8 are provided on the left and right of the front end of the above-mentioned frame 7. The above-mentioned limit seats 8 are provided with through holes. The rear end of the above-mentioned leg bracket 3 is parallelly extended with two insertion rods 9 aligned with the positions of the above-mentioned through holes. The above-mentioned insertion rods 9 are telescopically connected to the above-mentioned through holes, so that the above-mentioned insertion rods 9 can be extended into the interior of the above-mentioned seat plate 2, wherein the end of the above-mentioned insertion rod 9 is provided with an anti-drop structural member 10, and the above-mentioned anti-drop structural member 10 can prevent the above-mentioned insertion rod 9 from completely detaching from the above-mentioned seat plate 2. The above-mentioned anti-drop structural member 10 can be a nut with an outer diameter larger than the above-mentioned through hole, which is screwed and fixed to the end of the above-mentioned insertion rod 9, or it can be a connecting rod connected between the ends of the two above-mentioned insertion rods 9.

[0029] In this embodiment, the two above-mentioned insertion rods 9 are provided with a folding section 11 and a plug-in section 12, the above-mentioned folding section 11 is connected between the above-mentioned leg bracket 3 and the plug-in section 12, and a rotating portion 13 that can be rotated 90 degrees is provided between the above-mentioned folding section 11 and the plug-in section 12 and between the above-mentioned leg bracket 3 and the folding section 11 so that the above-mentioned folding section 11 and the leg bracket 3 can be bent downward. The above-mentioned insertion rod 9 can be bent twice to store the above-mentioned folding section 11 and the leg bracket 3 under the above-mentioned seat base 1, and the above-mentioned plug-in section 12 is stored in the above-mentioned seat plate 2, and the above-mentioned rotating portion 1 3 can be rotated within the range of 0 to 90 degrees. The rotating portion 13 is preferably a rotating joint or hinge. When unfolded, the junction of the end faces of the folding section 11 and the plug-in section 12 and the junction of the end faces of the leg bracket 3 and the folding section 11 form an abutment constraint, so that the insertion rod 9 can remain horizontal and straight. Preferably, the leg bracket 3, frame 7 and backrest 4 are all structural members made of high-strength materials, such as high-strength steel or high-strength carbon fiber, so that the overall structure has higher structural strength and load-bearing capacity, and can safely and effectively transfer patients when used as a stretcher.

[0030] Furthermore, the seat base 1 is provided with a plurality of legs 14, which are evenly fixed on the bottom edge of the seat base 1. The legs 14 are fixed to the floor of the vehicle compartment by screws. The legs 14 are arranged so that there is a gap between the seat base 1 and the floor of the vehicle compartment, so that the leg bracket 3 can be accommodated in the gap after being folded, thereby saving space in the vehicle compartment.

[0031] As an optimization, it also includes a head support 15, which is provided with two inserting tubes 16, and the rear end of the backrest 4 is provided with two inserting holes 17 corresponding to the positions of the inserting tubes 16. The inserting tubes 16 are inserted into the inserting holes 17. When the patient sits or lies down, the head can be rested on the head support 15. The surface of the head support 15 is covered with a head pad, and the surface of the backrest 4 is covered with a back pad. The head pad and the back pad provide flexible cushioning and support to improve comfort.

[0032] It is worth noting that the above-mentioned head pad, back cushion and seat cushion are all detachable, and the detachable methods can be Velcro bonding, connecting buckles or strapping, etc. When used as a stretcher, they can be flexibly removed selectively to reduce the weight of the stretcher.

[0033] According to a preferred embodiment, the frame 7 is provided with a plurality of screw holes, the seat base 1 is provided with a plurality of circular holes corresponding to the positions of the screw holes, the seat plate 2 is fixed with the screw holes after the bolts pass through the circular holes, and the spacing between the seat base 1 and the floor of the vehicle makes it very convenient to disassemble and assemble the bolts, and there is enough space for the screwing operation.

[0034] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
