Description

Technical Field

[0001] The utility model relates to the technical field related to automobile seat structures, in particular to a seat back lumbar support air pump installation structure. Background Art

[0002] As people's requirements for car riding comfort become higher and higher, the complexity of car parts is also increasing. Take car seats as an example. Today's car seats are generally equipped with lumbar supports, which can provide support for the passenger's waist and relieve the fatigue of the passenger's waist. The passenger can adjust the position of the lumbar support by adjusting the lumbar support handwheel.

[0003] In the prior art, the seat lumbar support, air bag and air pump are all installed on the seat back. However, due to the limitations of the structural setting, after the air bag and the air pump are installed inside the seat back, there is insufficient space inside the seat back. When the passenger sits on the seat, the passenger's waist will come into contact with the air pump, which will cause a foreign body sensation, affecting the passenger's riding experience, increasing the fatigue of the passenger's waist, and affecting the passenger's experience. Utility Model Content

[0004] The utility model aims to provide a seat back lumbar support air pump installation structure, which can solve the problem that the seat back installation space is insufficient, resulting in a foreign body sensation when the passenger's waist leans on the seat back.

[0005] To this end, the technical solution adopted by the utility model is: a seat back lumbar support air pump mounting structure, including an inner side panel of a seat frame, a mounting sheet metal for mounting an air pump is fixedly installed below the inner side panel, the air pump is fixed to the mounting sheet metal through a mounting assembly, and the air pump is connected to the lumbar support arranged in the seat back.

[0006] More preferably, the mounting sheet metal is bent into an "L" shape, including a horizontal plate and a vertical plate, and the upper end of the vertical plate is connected to the inner end of the horizontal plate, the upper surface of the horizontal plate is welded to the inner side plate, and the mounting assembly is arranged on the vertical plate. The air pump is mounted on the vertical plate, and the vertical plate is arranged on the inner side of the horizontal plate. When passengers are riding, they will not touch the air pump, which will not cause a foreign body sensation, and the air pump can be protected.

[0007] Further preferably, the mounting assembly includes two mounting rings arranged on the inner side of the mounting sheet metal, the mounting ring is provided with a mounting base on a side close to the mounting sheet metal, and the mounting base is provided with a threaded rod passing through a side wall of the mounting sheet metal and fixed by a nut.

[0008] Further preferably, the air pump is provided with an air intake line connected to the lumbar support, the air intake line includes a seat section and a backrest section, and a butt joint is provided at the connection between the seat section and the backrest section. The butt joint is provided to ensure that the seat section and the backrest section of the air intake line are firmly connected, and to avoid gas leakage, which may cause the lumbar support to fail to work properly.

[0009] More preferably, a plurality of mounting bases are arranged at intervals on the air intake pipeline of the seat section and the backrest section. By arranging the mounting bases on the air intake pipeline of the seat section and the backrest section, the air intake pipeline can be easily fixed.

[0010] More preferably, the air pump is provided with a wiring harness fixed on the mounting sheet metal through the mounting base. The wiring harness of the air pump is fixed on the mounting sheet metal to facilitate the connection and fixation of the wiring harness.

[0011] More preferably, the gap between the air pump and the extraction surface at the highest position of the seat slide rail is between 8 and 9 mm, so as to prevent the air pump from contacting the seat slide rail, thereby interfering with the seat slide rail and preventing it from working normally.

[0012] The beneficial effects of the utility model are as follows: by arranging a mounting sheet metal under the inner side panel of the seat frame and bending the mounting sheet metal to form an "L" shape, it is convenient to connect with the seat frame and protect the air pump; the air pump is installed in the mounting sheet metal, thus saving the internal installation space of the seat back; and the air pump is connected to the lumbar support, thus avoiding the situation in which the passenger's waist leans against the seat back due to insufficient internal installation space of the seat back, causing a foreign body sensation while riding, thereby affecting the passenger's riding experience.

[0016] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0017] like Figure 1-3 As shown, a seat back lumbar support air pump mounting structure includes an inner side panel 1 of a seat frame, a mounting sheet metal 3 for mounting an air pump 2 is welded below the inner side panel 1, the air pump 2 is fixed to the mounting sheet metal 3 through a mounting assembly, and the air pump 2 is connected to the lumbar support arranged in the seat back.

[0018] The mounting sheet metal 3 is bent to form an "L" shape, including a horizontal plate and a vertical plate, and the upper end of the vertical plate is connected to the inner end of the horizontal plate, and the upper surface of the horizontal plate is welded to the inner side plate 1. The mounting assembly is set on the vertical plate, and the air pump 2 is mounted on the vertical plate, and the vertical plate is set on the inner side of the horizontal plate. When passengers are riding, they will not touch the air pump 2 and feel a foreign body, and the air pump 2 can be protected. The mounting assembly includes two mounting rings 4 arranged on the inner side of the mounting sheet metal 3, and the mounting ring 4 is provided with a mounting base 5 close to the side of the mounting sheet metal 3, and the mounting base 5 is provided with a threaded rod that passes through the side wall of the mounting sheet metal 3 and is fixed by a nut.

[0019] The air pump 2 is provided with an air intake line 6 connected to the lumbar support, and the air intake line 6 includes a seat section and a backrest section, and a butt joint is provided at the connection between the seat section and the backrest section. The butt joint is provided to ensure that the seat section and the backrest section of the air intake line 6 are firmly connected to avoid gas leakage, which may cause the lumbar support to fail to work properly.

[0020] Several mounting bases 5 are arranged at intervals on the air intake line 6 of the seat section and the backrest section. By arranging mounting bases 5 (not shown in the figure) on the air intake line 6 of the seat section and the backrest section, the air intake line 6 is conveniently fixed.

[0021] The air pump 2 is provided with a wiring harness 8 fixed on the mounting sheet metal 3 through a mounting base 5. The wiring harness of the air pump 2 is fixed on the mounting sheet metal 3 to facilitate the connection and fixation of the wiring harness.

[0022] The gap between the air pump 2 and the extraction surface at the highest position of the seat slide rail 9 is between 8 and 9 mm. This prevents the air pump 2 from contacting the seat slide rail 9, which interferes with the seat slide rail 9 and prevents it from working normally.

[0023] By setting a mounting sheet metal 3 under the inner side panel 1 of the seat frame and bending the mounting sheet metal 3 to form an "L" shape, it is convenient to connect with the seat frame and protect the air pump 2. The air pump 2 is installed in the mounting sheet metal 3 to save the internal installation space of the seat back, and the air pump 2 is connected to the lumbar support to avoid the passenger's waist leaning on the seat back due to insufficient internal installation space of the seat back, thereby preventing the passenger from feeling a foreign body while sitting. This affects the passenger's riding experience.

[0024] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
