Description

Technical Field

[0001] The utility model relates to the technical field of automobile seat neck rests, in particular to a neck rest mechanism with airbag adjustment and a headrest with the neck rest mechanism. Background Technique

[0002] A neck rest is a functional component integrated on the top of an automobile seat or under the headrest. It is mainly used to support the necks of drivers and passengers, and can effectively avoid the discomfort caused by the lack of neck support during long-term driving or riding.

[0003] In the prior art, most neck rests are fixed parts and cannot be adjusted. Although the current headrests have the function of adjusting back and forth, when the neck rest is integrated under the headrest, the distance between the neck rest and the headrest remains fixed. However, the distances between the back necks and the back of the heads of each occupant are different. Therefore, the existing neck rests are difficult to meet the personalized needs of different users, and the comfort needs to be optimized and upgraded urgently. Summary of the Utility Model

[0004] In view of this, one of the purposes of the present utility model is to provide a neck rest mechanism with airbag adjustment, aiming to realize that the neck rest can be independently adjusted back and forth freely to meet the needs of different users.

[0005] To achieve the above purpose, the technical solution of the present utility model is as follows:

[0006] A neck rest mechanism with airbag adjustment includes a main mounting frame and a support assembly. The main mounting frame is used to be integrated in the headrest. A through hole extending in the front-back direction of the headrest is provided on the main mounting frame. The front part of the support assembly is used to support the neck of the occupant, and the rear part is slidably assembled in the through hole. It is characterized in that: an airbag is provided between the main mounting frame and the support assembly. The airbag is connected with a gas supply component. The gas supply component is used to inflate and deflate the airbag. When the airbag is inflated and expanded, it can push the support assembly forward. When the airbag is deflated and contracted, it can pull the support assembly backward.

[0007] With the above structure, by inflating and deflating the airbag, the support assembly can be slid back and forth relative to the main mounting frame, and thus the function of adjusting the neck rest back and forth can be achieved. The overall structure is very simple.

[0008] Preferably: the support assembly includes a sliding part, a support main body and a face cover covering the surface of the support main body. The sliding part has a sliding rod extending backward. The sliding rod is slidably arranged in the through hole. With the above structure, the back-and-forth adjustment of the neck rest is realized by the sliding of the sliding rod in the through hole.

[0009] Preferably, the front end of the support body is in an arc structure. Two massage air bags are symmetrically arranged at the middle position of the front end of the support body, and the massage air bags are connected with an air supply component. With the above structure, the arc structure design is more convenient for supporting the occupant's neck, and inflating and deflating the massage air bags can play a role in massaging the occupant's neck.

[0010] Preferably, the through hole is a rectangular hole, the sliding rod is configured as a rectangular rod adapted to the through hole, a limiting protrusion is arranged at the rear end of the sliding rod, the limiting protrusion protrudes from the side of the sliding rod, and a guiding inclined surface is arranged at the rear end of the limiting protrusion. With the above structure, the arranged limiting protrusion can prevent the main mounting frame and the support assembly from separating, and the guiding inclined surface helps the installation of the support assembly.

[0011] Preferably, the main mounting frame has a groove structure with an open front end. The sliding part is provided with an installation part extending backward into the groove structure. The air bag is circumferentially configured as a telescopic folding shape, one end of which is connected to the bottom of the groove structure, and the other end is connected to the rear end of the installation part. With the above structure, the air bag can be inflated and deflated in the groove structure, thereby ensuring more stable telescoping of the neck rest. The air bag being circumferentially configured as a telescopic folding shape ensures that the air bag can telescopically move in a fixed direction when inflated and deflated.

[0012] Preferably, the cross section of the groove structure is adapted to the cross section of the air bag. A first mounting hole is arranged at the bottom of the groove structure, and the first mounting hole is used for passing through and connecting the trachea between the air bag and the air supply component. With the above structure, the arranged first mounting hole can facilitate the installation of the trachea, thereby making the overall structure more compact.

[0013] Preferably, two through holes are arranged on the main mounting frame, and the two through holes are symmetrically arranged on the left and right sides of the groove structure. With the above structure, it further ensures that the neck rest can be adjusted more stably in the front - rear sliding direction.

[0014] Preferably, an installation groove extends backward from the middle position of the front end of the support body. The massage air bag is arranged in the installation groove. Two second mounting holes are symmetrically arranged on the installation groove, and the second mounting holes are used for passing through the trachea between the massage air bag and the air supply component. With the above structure, the arranged installation groove can reduce the overall thickness of the support assembly, and the arranged second mounting holes also further make the overall structure of the neck rest more compact.

[0015] Preferably, an emergency exhaust valve is connected to the distal end of the air bag, and the emergency exhaust valve is independently controlled by the vehicle passive safety system. With the above structure, it can ensure that when a vehicle collision occurs, the air bag can collapse, thereby reducing the injuries suffered by the occupant's neck and head.

[0016] Another object of the present utility model is to provide a headrest, which is characterized in that a neck support mechanism with the above-mentioned airbag adjustment is installed at the bottom of the front side of the headrest.

[0017] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0018] 1. By adopting the airbag-adjustable neck support mechanism provided by the present utility model and the headrest with this neck support mechanism, the support component is slidably installed on the main mounting frame, and an airbag is arranged between the support component and the main mounting frame. By inflating and deflating the airbag, the support component can slide back and forth relative to the main mounting frame, thereby realizing the independent front-back adjustment of the neck support relative to the headrest, meeting the support requirements of different occupants for the neck support, and having better comfort.

[0019] 2. By setting the support body into an arc structure and additionally installing two massage airbags at the front end of the support body, the neck support can not only well support the occupant's neck but also play a role in massaging the occupant's neck.

[0020] 3. The additionally provided emergency exhaust valve can deflate the airbag when the vehicle collides, so that the neck support collapses, thereby reducing the injuries suffered by the occupant's neck and head. Description of the Drawings

[0031] The present utility model will be further described below in conjunction with embodiments and the accompanying drawings.

[0032] Embodiment 1:

[0033] As shown in Figure 1 , Figure 2 , Figure 4 and Figure 8 , an airbag-adjustable neck support mechanism includes a main mounting frame 1 and a support assembly A. The main mounting frame 1 is used to be integrated in the headrest. A through hole 1a is formed in the main mounting frame 1 along the front-back direction of the headrest. The front part of the support assembly A is used to support the occupant's neck, and the rear part is slidably assembled in the through hole 1a. An airbag 2 is also installed between the main mounting frame 1 and the support assembly A. The airbag 2 is connected to a gas supply component 9 through a trachea 8. In this embodiment, the gas supply component 9 is selected as an air pump. The gas supply component 9 is used to inflate and deflate the airbag 2. When the airbag 2 is inflated and expanded, it can push the support assembly A forward. When the airbag 2 deflates and contracts, it can pull the support assembly A backward.

[0034] With such a design, by inflating and deflating the airbag 2 through the gas supply component 9, the support assembly A can slide back and forth relative to the through hole 1a, thereby achieving the purpose of adjusting the neck support back and forth and meeting the needs of different occupants for the neck support.

[0035] As shown in Figure 3 and Figure 6 , the support assembly A includes a sliding member 3, a support main body 4, and a face cover 5 covering the surface of the support main body 4. Among them, the sliding member 3 extends backward with a sliding rod 3a, and the support assembly A is slidably arranged in the through hole 1a through the sliding rod 3a. In this embodiment, a lock catch 3c is formed at the front end of the sliding member 3, and a lock hole 4c is formed at the rear end of the support main body 4. By inserting the lock catch 3c into the lock hole 4c, the sliding member 3 and the support main body 4 are fixedly installed.

[0036] Further, as shown in Figure 3 , the front end of the support main body 4 is in an arc structure. With such a design, it can better support the occupant's neck. An installation groove 4a is formed at the middle position of the front end of the support main body 4. Two massage airbags 6 are symmetrically installed on the left and right inside the installation groove 4a. A second installation hole 4b is also formed on the installation groove 4a. The second installation hole 4b is mainly used for passing through the trachea 8. The massage airbags 6 are connected to the gas supply component 9 through the trachea 8, and by inflating and deflating the massage airbags 6 through the gas supply component 9, the massage effect on the occupant's neck can be realized.

[0037] In this embodiment, through the combined design of the airbag 2 and the massage airbag 6, when the occupant's neck is supported on the support assembly A, it is not a completely rigid support, but has a certain flexibility, which further ensures the overall comfort of the occupant during use.

[0038] As Figure 4 and Figure 5 shown, in this embodiment, the through hole 1a is configured as a rectangular hole, and the sliding rod 3a is also configured as a rectangular rod adapted to the through hole 1a. Moreover, on the upper and lower sides of the rear end of the sliding rod 3a, there are frontward-extending limiting protrusions 3a1. The limiting protrusions 3a1 can effectively prevent the support assembly A from detaching from the main mounting frame 1, and a guiding inclined surface 3a2 is provided at the rear end of the limiting protrusion 3a1, so as to facilitate the installation of the support assembly A on the main mounting frame 1.

[0039] As Figure 4 and Figure 7 shown, a groove structure 1b with an open front end is formed at the middle position of the main mounting frame 1. The cross-section of the groove structure 1b is adapted to the cross-section of the airbag 2. In this embodiment, the cross-sections of the groove structure 1b and the airbag 2 are both rectangular structures. The rear end of the airbag 2 is fixedly connected to the innermost side of the groove structure 1b. At the middle position of the rear end of the sliding member 3, there is a rearward-extending mounting portion 3b. The front end of the airbag 2 is fixedly connected to the rear side of the mounting portion 3b. In this embodiment, the airbag 2 is fixedly connected between the main mounting frame 1 and the support assembly A by bolts. At the center position of the rear side of the groove structure 1b, there is a first mounting hole 1b1 for passing through an air pipe 8 to facilitate the connection between the airbag 2 and the air supply component 9.

[0040] As Figure 7 shown, in this embodiment, the airbag 2 is circumferentially configured in a telescopic and foldable shape, so as to ensure that the expansion and contraction directions of the airbag 2 are fixed when it is inflated and deflated. When the airbag 2 is full, the extended length of the airbag 2 is consistent with the depth of the groove structure 1b. In this way, it can be ensured that during the inflation and deflation process of the airbag 2, there is support in its circumferential direction, and further, the support assembly A can slide more stably back and forth.

[0041] To further ensure that the support assembly A slides more stably relative to the main mounting frame 1, in this embodiment, two through holes 1a are formed on the main mounting frame 1, and the two through holes 1a are symmetrically arranged on the left and right sides of the groove structure 1b. The sliding member 3 extends backward with a sliding rod 3a corresponding to each through hole 1a.

[0042] Again, as Figure 4 shown, on the left and right sides of the main mounting frame 1, there are third mounting holes 1c distributed in the vertical direction. The third mounting holes 1c are mainly used for passing through the installation guide rod 11 between the vehicle headrest and the vehicle seat. At the middle position of the top of the main mounting frame 1, there is also an upwardly formed mounting buckle 1d, and the mounting buckle 1d is used for fixedly connecting with the bottom of the vehicle headrest.

[0043] As Figure 8 shown, in this embodiment, the distal end of the airbag 2 is also connected with an emergency exhaust valve 7 through a trachea 8. The emergency exhaust valve 7 is independently controlled by the vehicle passive safety system. Under normal circumstances, the emergency exhaust valve 7 is in a closed state. When an emergency such as a vehicle collision occurs, the vehicle passive safety system controls the emergency exhaust valve 7 to open, and the airbag 2 can exhaust gas, so that the support assembly A can collapse backward, effectively reducing the impact force received by the occupant's neck and head and ensuring the safety of the occupant.

[0044] Embodiment 2:

[0045] As Figure 9 and Figure 10 shown, a headrest mainly includes a headrest main body 10, and an airbag-adjustable neck support mechanism described in Embodiment 1 is fixedly installed at the lower end inside the headrest main body 10. In this embodiment, the airbag-adjustable neck support mechanism is clamped to the bottom of the headrest main body 10 through a mounting buckle 1d provided at the top of the main mounting frame 1 to achieve the fixed installation between the headrest main body 10 and the airbag-adjustable neck support mechanism. With such a design, by inflating and deflating the airbag 2, the front-back distance between the headrest main body 10 and the support assembly A can be changed, thereby meeting the neck support requirements of different occupants.

[0046] Finally, it should be noted that the above description is only the preferred embodiment of the present invention. Under the inspiration of the present invention, those of ordinary skill in the art can make various similar representations without departing from the purpose and claims of the present invention. Such changes all fall within the protection scope of the present invention.
