The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be understood as limiting the present invention.
[0019] First embodiment:
[0020] See also Figures 1 to 4 ,in Figure 1 This is a schematic diagram of the overall structure of the middle row single seat. Figure 2 yes Figure 1 A magnified image of Figure 3 This is a schematic diagram of the installation structure of the handrail. Figure 4 yes Figure 3 Enlarged view of point B.
[0021] The utility model provides a middle row single-seat chair, including a base 101, a seat cushion 102, a backrest 103 and an adjustment component 104, wherein the adjustment component 104 includes an adjuster 105, a rotating member 106, a cable 107, a pulling member 108, a fixed shaft 109, an armrest 110, a locking member 111, a first connecting member 112, a second connecting member 113, a sheath 114, a tension spring 115, a torsion spring 116 and a third connecting member 117. By changing the adjuster 105 to an unlocking structure on the inner side of the backrest 103, and the pulling member 108 is on the outer side of the backrest 103 away from the armrest 110, it is convenient to operate. It can be understood that the above scheme can be used to reduce costs while not reducing the structural strength of the backrest 103, and it is convenient to operate, and it can also be used to lock and unlock the armrest 110.
[0022] For this specific embodiment, the seat cushion 102 is slidably installed on the base 101, the backrest 103 is rotatably installed on the seat cushion 102, and the base 101 is installed on the car. The seat cushion 102 can slide on the base 101 to adjust the distance between the seat cushion 102 and the front seat. A locking structure is also provided on the seat cushion 102, which can lock the seat cushion 102 on the base 101. The locking structure is a prior art and will not be described in detail here.
[0023] The recliner 105 is connected to the seat cushion 102 and to the backrest 103, and is arranged on the seat cushion 102; the rotating member 106 is arranged on the recliner 105 and is connected to the input end of the recliner 105; the pulling member 108 is rotatably connected to the backrest 103 and is arranged on the backrest 103; the two ends of the cable 107 are respectively connected to the rotating member 106 and the pulling member 108; the cable 107 is arranged on the rotating member 106; the fixed shaft 109 is fixedly connected to the backrest 103 and is arranged on the backrest 103; the armrest 110 is rotatably connected to the fixed shaft 109 and is arranged on the fixed shaft 109; the locking member 111 is arranged on the armrest 110; the recliner 105 can lock and The unlocking operation, the recliner 105 is a prior art, and its structure and principle are not described in detail here. The armrest 110 and the recliner 105 are both installed on the inner side of the backrest 103, which increases the strength and rigidity of the inner side. When the angle of the backrest 103 needs to be adjusted, the user pulls the pulling member 108 to drive one end of the cable 107 to move, and then the other end of the cable 107 pulls the rotating member 106 to rotate, thereby driving the input end of the recliner 105 to rotate. At this time, the recliner 105 is unlocked, so that the angle of the backrest 103 can be adjusted. In this solution, the recliner 105 is changed to an unlocking structure on the inner side to increase the strength and rigidity of the inner side. The outer side is a mechanism for controlling the unlocking. Without reducing the structural strength, the unlocking operation avoids the armrest 110 on the inner side, which is convenient for operation.
[0024] Secondly, the first connecting member 112 is fixedly connected to the seat cushion 102 and is located on a side of the seat cushion 102 close to the pulling member 108; the second connecting member 113 is fixedly connected to the seat cushion 102 and is located on a side of the seat cushion 102 close to the rotating member 106; the two ends of the sheath 114 are respectively connected to the first connecting member 112 and the second connecting member 113, and the sheath 114 is sleeved on the cable 107; the cable 107 is protected by the sheath 114 to prevent the cable 107 from being exposed to the outside and causing wear or jamming when pulled.
[0025] At the same time, the two ends of the tension spring 115 are respectively connected to the rotating member 106 and the second connecting member 113, and the tension spring 115 is arranged on the second connecting member 113; when the cable 107 pulls the rotating member 106 to rotate, thereby unlocking the adjuster 105, the rotating member 106 stretches the tension spring 115; in this way, after the angle of the backrest 103 is adjusted to the right position, the pulling member 108 is released, and the rotating member 106 can be reset under the action of the tension spring 115, thereby resetting the input end of the adjuster 105, thereby re-locking the backrest 103.
[0026] In addition, the third connecting member 117 is fixedly connected to the backrest 103 and is located on one side of the backrest 103; the two ends of the torsion spring 116 are respectively connected to the seat cushion 102 and the third connecting member 117, and the torsion spring 116 is arranged on the seat cushion 102; through the torsion spring 116, after the angle adjuster 105 is unlocked, the backrest 103 can automatically tilt forward under the action of the torsion spring 116, so as to facilitate the user to adjust the angle of the backrest 103.
[0027] When using the middle row single-seat seat of this embodiment, the user pulls the pulling member 108 to drive one end of the cable 107 to rotate, and then the other end of the cable 107 pulls the rotating member 106 to rotate, and the rotating member 106 stretches the tension spring 115 while driving the input end of the recliner 105 to rotate, so that the recliner 105 is unlocked, and the angle of the backrest 103 can be adjusted at this time; when the angle of the backrest 103 is adjusted to the right angle, the pulling member 108 is released, and the rotating member 106 is reset under the action of the tension spring 115, so that the input end of the recliner 105 is reset, so that the backrest 103 is locked again. The present invention changes the recliner 105 into an unlocking structure on the inside to increase the strength and rigidity of the inside, and the outside is a mechanism for controlling the unlocking. Without reducing the structural strength, the unlocking operation avoids the armrest 110 on the inside, which is convenient for operation.
[0028] Second embodiment:
[0029] Based on the first embodiment, please refer to Figure 5 , Figure 5 2 is a schematic structural diagram of a locking member according to a second embodiment. The locking member 111 of this embodiment includes a ratchet 201 , a pawl 202 and a locking spring 203 .
[0030] According to the present specific embodiment, the ratchet 201 is fixedly connected to the fixed shaft 109 and is located inside the armrest 110; the pawl 202 is rotatably connected to the armrest 110 and is located inside the armrest 110; the two ends of the locking spring 203 are respectively connected to the pawl 202 and the armrest 110, and the locking spring 203 is located inside the armrest 110; a knob is also installed on the outer side of the pawl 202; through the ratchet 201 and the pawl 202, the armrest 110 can only be moved. One-way rotation, when using the armrest 110, the user directly rotates the armrest 110 to extend the armrest 110. At this time, the armrest 110 cannot rotate in the opposite direction under the action of the ratchet 201 and the pawl 202, thereby facilitating the passenger to support the armrest 110. When the armrest 110 is not in use, the knob on the pawl 202 is rotated to disengage the pawl 202 from the ratchet 201. At this time, the armrest 110 can be reset and retracted, thereby achieving the purpose of locking and unlocking the armrest 110.
[0031] What is disclosed above is only one or more preferred embodiments of the present application, and cannot be used to limit the scope of rights of the present application. Ordinary technicians in this field can understand that all or part of the processes of implementing the above embodiments and equivalent changes made according to the claims of the present application are still within the scope covered by the present application.
