Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of seats, in particular to a seat with a flippable and switchable headrest. Background Art
[0002] In order to support the back of the human body, a backrest can be installed at the rear of the seat, and the back is supported by the inclination of the backrest. In addition, a headrest can be installed on the top of the backrest to additionally support the head of the human body.
[0003] In the prior art, the headrest of the seat is usually fixed and cannot be removed, or can only be simply adjusted in angle or height. For a normal sitting posture, the back of the human body can contact the backrest of the seat, but the waist is usually suspended and cannot contact the backrest, and an additional waist support is usually required. The additional waist support is usually placed at the end of the base, which not only occupies the area of the base, but is also easy to fall off, and needs to be improved. Utility Model Content
[0004] The utility model aims to provide a seat with a flippable headrest, so that the headrest can be flipped and switched to a lumbar support, thereby improving the convenience of use.
[0005] To achieve this purpose, the utility model adopts the following technical solutions:
[0006] A seat with a flippable headrest comprises: a headrest, a base and a backrest, wherein the bottom of the backrest is connected to the tail of the base, a first pin is horizontally arranged in the backrest, a second pin is horizontally arranged in the headrest, a connecting rod is arranged between the first pin and the second pin to support the flipping of the headrest between the top of the backrest and the lower front part of the backrest, and a first stopper is arranged in the backrest, which is located above the first pin and limits the position of the connecting rod after flipping up.
[0007] Wherein, the number of the connecting rods is 2.
[0008] Wherein, the backrest comprises a bracket and a cushion, and the cushion is arranged on the front side of the bracket.
[0009] Wherein, the bracket is provided with a first pin seat corresponding to the first pin shaft, and the cushion is provided with an avoidance groove corresponding to the connecting rod.
[0010] Wherein, a second pin seat corresponding to the second pin shaft is arranged in the headrest.
[0011] Wherein, a second stopper is arranged at the bottom of the headrest to limit the flipping of the headrest relative to the connecting rod.
[0012] The beneficial effects of the utility model include: a seat with a flippable headrest, which can support the human head when lying down, and can be flipped on the support of a connecting rod when sitting upright, and after flipping down, it is located at the lower front part of the backrest, replacing the lumbar support to support the waist, has a stable structure, and is easy to switch, without the need to install an additional lumbar support, thus meeting different usage requirements.

[0016] Figure 4 yes Figure 1 Schematic diagram of the structure after the middle headrest is folded down. DETAILED DESCRIPTION
[0017] Combine the following Figure 1 to Figure 4 The technical solution of the utility model is further illustrated by specific embodiments.
[0018] like Figure 1 and Figure 2 The seat with a flippable headrest as shown comprises a headrest 5, a base 1 and a backrest 2, wherein the bottom of the backrest 2 is connected to the rear of the base 1, and the backrest 2 can support the back of the human body.
[0019] The backrest 2 is provided with a first pin 3 horizontally, the headrest 5 is provided with a second pin 6 horizontally, and a connecting rod 7 is provided between the first pin 3 and the second pin 6 to support the headrest 5 to flip between the upper part of the backrest 2 and the lower part of the front of the backrest 2. Figure 3 and Figure 4 As shown, the headrest 5 is flipped down under the action of the connecting rod 7. At the same time, the headrest 5 is flipped counterclockwise relative to the connecting rod 7 under the action of the second pin 6, so that the headrest 5 can be close to the lower front part of the backrest 2, thereby improving the structural stability after switching.
[0020] like Figure 1 As shown, the backrest 2 is provided with a first stopper 4 located above the first pin shaft 3 for limiting the position of the connecting rod 7 after it is flipped up. The first stopper 4 is used to limit the connecting rod 7 when it is flipped up counterclockwise to the top of the backrest 2, thereby preventing the connecting rod 7 from continuing to flip over. At this time, the headrest 5 is located above the backrest 2 to support the human head.
[0021] like Figure 2As shown, a second stopper 8 is provided at the bottom of the headrest 5 to limit the flipping of the headrest 5 relative to the connecting rod 7. At this time, the second stopper 8 limits the clockwise flipping of the headrest 5, thereby improving the stability of the head support for the human body.
[0022] In this embodiment, the number of the connecting rods 7 is two, which improves the stability of the support for the headrest 5. Figure 3 As shown, the backrest 2 includes a bracket 21 and a cushion 22, wherein the cushion 22 is arranged on the front of the bracket 21. The bracket 21 can be a steel pipe structure with high strength and good support for the cushion 22. In addition, an avoidance groove corresponding to the connecting rod 7 is arranged in the cushion 22, which does not affect the turning of the connecting rod 7 relative to the cushion 22.
[0023] A first pin seat corresponding to the first pin shaft 3 is provided in the bracket 21, and a second pin seat corresponding to the second pin shaft 6 is provided in the headrest 5, which improves the turning flexibility of the connecting rod 7 and the headrest 5. Figure 4 As shown, the headrest 5 can be quickly flipped over and switched to be used as a lumbar support to meet different usage requirements.
[0024] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there will be changes in the specific implementation methods and application scopes. The contents of this specification should not be understood as limiting the present invention.
