Air cushion headrest structure for vehicles

The present invention relates to a vehicle air cushion headrest structure; in particular, a vehicle seat headrest application body combined air cushion portion, which is operated with an inflator to elastically adjust the size of the air cushion portion to meet different driving needs and ergonomics of the driver. The new type.

It is a well-known skill to provide a headrest for a vehicle seat to support the driver's head and to relieve neck and spine burden and fatigue. Such seat headrest structures are generally coated with leather, cloth fabric, a thin layer of plastic, etc., covering the shape of the filler, foam or the like. And a connecting rod and a pivoting component are arranged between the headrest and the seat, so that the headrest can be rotated to adjust the front and rear tilting angles to support the driver's head.

One of the problems in the structure and application of such a vehicle headrest is that the conventional headrest structure is not made according to the different head shape of the driver or the actual use of the driver, so the headrest is made. Contours or specifications are fixed and can only provide basic support, failing to achieve true protection and full, complete support.

In particular, the conventional headrest structure causes the driver's cervical vertebrae to be suspended, which not only has insufficient support, but also causes cervical soreness caused by long-term driving of the user, affecting driving safety, etc.; It is ergonomic.

In order to improve the above situation, the old method discloses a headrest structure of a combinable seat; for example, Taiwan Patent No. 81204882 "Structural Improvement of the Pillow" provides a typical embodiment. In the embodiment, a side pad for inflating the mouth is provided on both sides of the headrest body, and an elastic strap is arranged on the back of the headrest body to fit on the seat for supporting the user's head.

However, as is known to those skilled in the art, in the actual use of the above embodiment, the headrest body still causes the user's cervical vertebra to form a floating state, which is disadvantageous for the user to drive for a long time. Moreover, the above embodiment is only applicable to a structural module having a higher seat back; for example, a passenger seat of a large vehicle can position the headrest at a height position of the seat back, in accordance with the user's ride. The height of the head is supported.

The structural form of the above embodiment cannot be applied to a general car seat, particularly a driver's seat. This is because if the elastic strap of the headrest body fits over the car seat, the height of the headrest body does not match (ie, is lower than) the height of the head when the driver is riding, which is not advantageous to the driver. If the elastic strap of the headrest body fits over the headrest of the car seat, the overlapping thickness of the headrest body and the headrest of the car seat will cause the driver's head to be excessively forward and the cervical spine to hang, not only Not conducive to the driver, nor the actual driving position and ergonomic conditions.

Conventional techniques have also revealed a number of inflatable headrest structures for use in sleeping; for example, Taiwan No. 88211944 "Pillow Inflatable Structure", No. 94111168 "Adjustable Gas-Liquid Composite Pillow", No. 103221538 "Inflatable Adjustment" A typical embodiment is provided by the "Pillow" patent and the like. They provide an inflatable structure that adjusts the amount of fluid inside the headrest so that the headrests have different heights to meet the different practical needs of the person.

It can be understood that the headrest structure (hereinafter referred to as a sleeping headrest) used by such a provider to sleep can not be applied to a car seat. Reasons include:

1. The part of the headrest that contacts the head of the sleeping head must be a whole flat structure, in order to provide a supporting role for the relative change or displacement of the person's head when the sleeping position of the person is changed, and to reduce the condition of the stiff neck. Therefore, the two sides of the sleeping headrest are not suitable for forming a protruding structure.

2. It is known that lying pillows do not support the structure of the cervical spine; in order to avoid the person lying down, the head is over-rear, causing snoring. And these situations are not what we expect.

Typically, these references show the design techniques for the structure and application of conventional headrests or vehicle seat headrests; they also reflect some of the problems with these headrests in actual use. . If the re-design considers the combination structure of the headrest, it is ergonomically designed to make it different from the conventional vehicle seat headrest, which will provide an ideal protection and support ability, and improve the conventional knowledge. The shortcomings of the craft.

We found that the car seat headrest structure must consider the following topics:

1. Removal or conversely, the conventional lying headrest provides an overall (contact) planar structural pattern; in particular, a protruding structure is formed on both sides of the headrest, and the protruding structure is allowed to have an elastic adjustment or size. .

2. It is necessary to improve the structure of the conventional structure (including the car seat headrest and the sleeping headrest) without the support of the cervical vertebrae of the person, so that the driver's cervical vertebrae are in a suspended state, and there is insufficient support, resulting in the driver's cervical vertebrae. The department is sore and affects the safety of driving.

3. It is necessary to provide a car seat headrest structure that can be elastically adjusted or changed to improve the structure of the conventional vehicle seat headrest, which is not based on the different head contours of the driver or the actual use requirements. The headrest profile or specification is fixed and can only provide basic support, and can not achieve the actual protection and complete and complete support effects. None of these topics have been taught or specifically disclosed in the above references.

Therefore, the main purpose of the present invention is to provide a vehicle air cushion headrest structure comprising a combination of a headrest body, an air cushion portion provided on the body, and an inflator connected to the air cushion portion. The inflator has a pump and a gas pipe connected to the pump; the gas pipe is connected to the air cushion portion; and the operating pump controls the fluid to enter the air cushion portion, and elastically adjusts the size of the air cushion portion to achieve different head shape and/or actual use requirements according to the driver. In the ergonomic condition, the body and the air cushion part can protect the driver's head and cervical vertebrae.

According to the air cushion headrest structure of the present invention, the body defines an intermediate area, two side areas, an upper area, and a lower area. And, corresponding to the driver's cervical vertebra, the air cushion portion includes a main air cushion portion, and the coupling is disposed in a lower region of the body. The main air cushion part can be provided according to the actual use requirement of the driver, or the degree of suspension between the cervical vertebra and the body (or the range of the suspended area), and the fluid injection amount is elastically adjusted to compensate the suspension degree to provide the driver (the cervical vertebra) Department and / or head) the effect of the protection and complete and complete support. The compensation refers to a situation in which the main air cushion portion fills the range of the suspended area.

According to the air cushion headrest structure of the present invention, the air cushion portion includes a first air cushion portion and a second air cushion portion, which are disposed on two sides of the body; the first air cushion portion and the second air cushion portion respectively have a contact with the head of the person surface. And the gas pipe of the inflator comprises a first pipe and a second pipe connecting the main pipe and the main pipe; the first pipe is connected to the first air cushion portion, and the second pipe is connected to the second air cushion portion, and the pump is injected into the first air cushion portion, The second air cushion portion adjusts the size of the first air cushion portion and the second air cushion portion so that the contact surface contacts and protects both sides of the support person's head.

Please refer to Figures 1 and 2 for the air cushion headrest structure of the present invention, including a headrest body that can be mounted on a vehicle seat, which is indicated by reference numeral 10. The upper, lower, two sides, etc. mentioned in the following description are based on the direction shown in the figure. The body 10 defines an intermediate portion 11, a two-sided region 12, and an upper region 13 and a lower region 14 in accordance with the position in the figure. And, the body 10 includes a combination of an air cushion portion 50 provided on the body 10 and an inflator 40 connected to the air cushion portion 50.

In the embodiment taken, the body 10 is bent from the intermediate region 11 in the direction of the two-sided region 12 such that the two-sided region 12 (relative to the intermediate region 11) forms a pattern of curved projections; A bend angle is formed between the two side regions 12 and the intermediate portion 11 such that the two side regions 12 enclose the sides of the guard or support person's head 20.

Corresponding to the driver's cervical vertebra 25, the air cushion portion 50 includes a main air cushion portion 55 that is coupled to the lower region 14 of the body 10. And, the inflator 40 has a pump 45 and an air duct 46 that connects the pump 45, and the air duct 46 is connected to the air cushion portion 50 (or the main air cushion portion 55). The pump 45 can be selected to be manually pressed or driven by an electric motor to inject fluid into the air cushion portion 50 (or the main air cushion portion 55) via the air duct 46.

Therefore, when the operating pump 45 controls the fluid to enter the air cushion portion 50 (or the main air cushion portion 55), the size of the air cushion portion 50 (or the main air cushion portion 55) can be elastically adjusted to achieve different head contours and/or actual use according to the driver. The requirement is that the body 10 and the air cushion portion 50 (or the main air cushion portion 55) are ergonomically protected to support the driver's head, cervical vertebrae and the like.

For example, FIG. 2 particularly depicts that the main air cushion portion 55 adjusts the amount of fluid injection according to the degree of suspension between the driver's cervical vertebra 25 and the body 10 (or the range of the suspended area) to compensate for the degree of suspension and provide driving. The person (cervical vertebra 25 and/or head 20) has a positive protection and a complete and complete support effect. The compensation refers to a case where the air cushion portion 50 (or the main air cushion portion 55) fills the range of the suspended region.

Therefore, like the conventional structure, the driver's cervical vertebrae are suspended, and there is insufficient support, which causes the cervical vertebrae pain caused by the user to drive for a long time, affects the safety of driving and the ergonomic effect, and is obviously improved.

Please refer to Figure 3 for a possible embodiment. The air cushion portion 50 includes a first air cushion portion 51 and a second air cushion portion 52 disposed on both side regions 12 of the body 10; therefore, the first air cushion portion 51, the second air cushion portion 52, and/or the body two-sided region 12 are collectively configured to form an arc. The shape of the protruding structure.

The first air cushion portion 51 and the second air cushion portion 52 correspond to the human head 20, which are generally in the shape of a half moon, each having a contact surface 53, 54 which may have a planar or curved surface structure. And, the gas delivery pipe 46 of the inflator 40 includes a main pipe 43 and a first branch pipe 41 and a second branch pipe 42 that connect the main pipe 43.

In the embodiment taken, the main pipe 43 and the first branch pipe 41 and the second branch pipe 42 form a "Y" or "T" shape structure. The first tube 41 is connected to the first air cushion portion 51, and the second branch portion 42 is connected to the second air cushion portion 52. The fluid is injected into the first air cushion portion 51 and the second air cushion portion 52 in cooperation with the pump 45 to adjust the first air cushion portion 51, The two air cushion portions 52 are sized such that the contact surfaces 53, 54 resiliently contact and protect the two sides of the support person's head 20.

The figure shows that the main pipe 43 penetrates into the body 10 such that the first branch pipe 41 and the second branch pipe 42 are positioned inside the body 10, and the first air cushion portion 51 and the second air cushion portion 52 are respectively connected.

Referring to Figures 4, 5 and 6, a modified embodiment is disclosed. The air cushion portion 50 includes a main air cushion portion 55 that is coupled to the lower region 14 of the body 10, and a first air cushion portion 51 and a second air cushion portion 52 that are disposed on both side regions 12 of the body 10. Further, the main air cushion portion 55 is formed with a mouth portion 56 at both ends thereof, and is connected to the first air cushion portion 51 and the second air cushion portion 52, respectively.

The air duct 46 (or main tube 43) of the inflator 40 is also shown coupled to the main air cushion portion 55. Therefore, when the pump 45 is operated to inject the fluid into the main air cushion portion 55 through the air duct 46, the fluid is also injected into the first air cushion portion 51 and the second air cushion portion 52 through the mouth portion 56 to adjust the main air cushion portion 55 and the first air cushion portion. The portion 51 and the second air cushion portion 52 are sized such that the main air cushion portion 55 elastically supports the driver's cervical vertebra portion 25, and the first air cushion portion 51, the second air cushion portion 52, and the contact surfaces 53, 54 are elastically contacted and assisted. Both sides of the person's head 20 provide the driver (the cervical vertebra 25 and/or the head 20) with substantial protection and complete and complete support; for example, the situation depicted in Figure 6.

Typically, the air cushion headrest structure of this vehicle includes the following advantages and considerations compared to the old method:

1. The combined structure of the body 10, the main air cushion portion 55, the first air cushion portion 51, the second air cushion portion 52, and the inflator 40 has been redesigned; for example, the body intermediate portion 11 is bent toward the two side regions 12 The arcuate protruding structure; the lower region 14 and/or the two side regions 12 of the body 10 are provided with a main air cushion 55 and/or a first air cushion portion 51 and a second air cushion portion 52; and an air duct 46 of the inflator 40 (including the main pipe 43 and / Or the first branch pipe 41 and the second branch pipe 42) are connected to the main air cushion portion 55 and/or the first air cushion portion 51 and the second air cushion portion 52; the two ends of the main air cushion portion 55 form a mouth portion 56, and the connection is connected to the first air cushion portion 51. The portion of the second air cushion portion 52 and the like is significantly different from the structural form of the prior art.

2. The combined structure of the body 10, the air cushion portion 50 and the inflator 40, the removal or opposite to the conventional lying headrest provides an overall (contact) planar configuration, and in the two sides 12 and/or combination first The air cushion portion 51 and the second air cushion portion 52 collectively form a protruding structure; and the protruding structure has an effect of allowing the elastic to adjust the size or the specification according to different head contours or practical operation requirements of the driver.

3. In particular, the lower region 14 of the body 10 is provided with the structural form of the main air cushion portion 55, and the function of the size change is flexibly controlled by the pump 45 and the air duct 46, and the conventional structure (including the vehicle seat) is improved. The headrest and the sleeping head pillow do not support the cervical vertebrae of the person, so that the driver's cervical vertebrae form a suspended state, and there is insufficient support, causing the driver's cervical vertebrae to suffer from pain and affecting driving safety.

4. The combined structure of the body 10, the air cushion portion 50 and the inflator 40 provides a vehicle seat headrest structure that can be elastically adjusted or changed in size, and also makes the conventional vehicle seat headrest structure not based on the driver. Made with different head profile or actual use requirements, headrest profile or specifications In a fixed form, it can only provide basic support, and it can not achieve the exact protection and complete and complete support effects, and all have achieved significant improvement.

Therefore, this creation department provides an effective air cushion headrest structure, which is different from the conventional ones in terms of space type, and has the advantages unmatched in the old law. It shows considerable progress and is fully fulfilled. Meet the requirements of the new patent.
