AI Technical Summary
The support surface of the traditional sofa headrest is single in shape and cannot effectively fit the shape of the back of the human body, resulting in unstable head and easy to deviate, affecting the sitting experience and physical health.
Airbags are installed on both sides of the inner cavity of the headrest. The support surface tends to be horizontal in the deflated state. The airbag expands and pushes the support surface in the inhalation state, so that it presents a concave structure with high and low middle on the left and right sides, which is more in line with the shape of the back of the human body.
Through the switching of the inhalation and deflation states of the airbag, the support surface of the headrest can provide stable and comfortable support in different states, reducing head offset, improving user experience, and meeting ergonomic requirements.

Abstract
Description
Technical Field
[0001] The utility model generally relates to the technical field of furniture, and in particular to an ergonomic headrest and a sofa. Background Art
[0002] Sofas are common seats in daily life. People sit or lie on sofas to rest, and they also watch TV, play with mobile phones and other entertainment activities while resting. In addition, in order to relax and relieve stress while sitting, consumers have high requirements for the comfort of sofa headrests.
[0003] Traditional sofa headrests usually have a leather or cotton outer layer and are filled with flexible materials such as PP cotton and down inside, providing a soft and comfortable experience. Some sofa headrests also have an airbag added inside, and the airbag can be expanded or contracted by adjusting a switch, thereby adjusting the hardness and softness of the headrest and the height of the headrest.
[0004] Although the traditional sofa headrest is relatively soft, its shape is relatively simple, and the support surface of the headrest is mostly horizontal or a curved surface structure convex to the front; even if the airbag headrest can change its shape, since only a single airbag is usually arranged in the headrest, no matter how the airbag expands or contracts, the support surface of the headrest is also horizontal or a curved surface structure convex to the front; and, as shown in the attached Figure 7 As shown, since the back of the human head is in the shape of an arc that bulges backwards, when the user's head rests on the headrest, the horizontal or forward-bulging support surface cannot fit the back of the user's head well, and the user's head cannot get stable support and is prone to shift to the left or right, causing the user to lie in a crooked position, which not only brings a poor sitting experience but is also not conducive to physical health. Summary of the invention
[0005] In view of the above defects or deficiencies in the prior art, it is desirable to provide an ergonomic headrest and sofa, by arranging airbags on both sides of the inner cavity of the headrest body, the support surface tends to be horizontal in the deflated state, and the headrest body can be used as a regular pillow; in the inhaled state, the airbags expand and push the support surface, so that the support surface presents a concave structure with high left and right sides and low middle, and the shape of the support surface is more in line with the shape of the back of the human head, and the user experience is more comfortable; and the user's head rests on the downwardly concave part in the middle of the support surface, and the head is clamped in the middle by the bulging airbags on both sides, and is not easy to deflect to the left or right. As a result, the headrest body can provide a stable and comfortable support effect for the user's head, which is ergonomic.
[0006] The effect of the utility model is achieved in this way:
[0007] In a first aspect, the present application provides an ergonomic headrest, comprising a headrest body, the headrest body comprising a support surface on the front side, the support surface being configured to support the user's head, the inner cavity of the headrest body being divided into left and right parts and provided with at least one pair of airbags, the airbags having switchable inhalation state and deflation state; in the deflated state, the airbags contract and the support surface tends to be horizontal; in the inhaled state, the airbags expand and push the support surface, the support surface presents a concave structure with higher left and right sides and lower middle, or the support surface presents a concave structure with higher left and right sides and lower middle when subjected to pressure, and the raised surface of the airbag forms an inclined stop within the support surface.
[0008] Furthermore, a plurality of airbags stacked in the vertical direction are arranged on either side of the left and right sides of the inner cavity of the headrest body, so that in the inhaled state, the expansion degree of a single airbag is smaller, its hardness is also lower, and the impact on the overall softness of the headrest body is also smaller.
[0009] Furthermore, on either side of the inner cavity of the headrest body, the ends of the airbags near the middle of the headrest body are connected to each other as a whole. In the inhaled state, the ends of the airbags near the left and right sides of the headrest body squeeze each other and stretch out, so that the support surface tends to be horizontal when not under pressure, and when under pressure, the support surface is concave downward along the inclined push surface of the airbag, and the shape fits the human head better.
[0010] Furthermore, three airbags stacked in the vertical direction are arranged on either side of the left and right sides of the inner cavity of the headrest body, which not only ensures the supporting effect of the headrest body, but also prevents the airbags from being too hard in the inhaled state and affecting the softness of the headrest body.
[0011] In the second aspect, the present application provides an ergonomic headrest, including a headrest body, the headrest body including a support surface on the front side, the support surface is configured to support the user's head, the inner cavity of the headrest body is divided into upper and lower parts and is provided with at least a pair of airbags, the airbags have switchable inhalation state and deflation state; in the deflation state, the airbags shrink and the support surface tends to be horizontal; in the inhalation state, the airbags expand and push the support surface, so that the support surface presents a U-shaped structure with high upper and lower sides and low middle. When the user's head rests on the downwardly concave part of the support surface, the protrusion on the lower side of the support surface can fit and support the user's neck, so that the headrest body can be used as a neck pillow to protect the health of the user's cervical spine.
[0012] In a third aspect, the present application provides a sofa, comprising a back cushion and an ergonomic headrest, wherein the headrest body is located at the top of the back cushion, and the back cushion further comprises a back support portion and a waist support portion, wherein air bags are arranged in the back support portion and the waist support portion, so that the user can adjust the contraction or expansion of the air bags, change the hardness and height of the back support portion and the waist support portion, select a suitable back cushion state, and improve the comfort of the sofa.
[0013] Furthermore, the sofa also includes a seat cushion, which is configured to support the user's buttocks, and a rotating mechanism is also provided at the bottom of the back cushion, so that the back cushion can rotate forward and backward relative to the seat cushion. Therefore, no matter the user is in a sitting position or a lying position, the back cushion can be adjusted to fit the user's back, providing reliable support and making it more practical.
[0014] The ergonomic headrest and sofa provided by the present application are provided with airbags on both sides of the inner cavity of the headrest body. In the deflated state, the airbags shrink and the support surface tends to be horizontal, so that the headrest body can be used as a conventional pillow; in the inhaled state, the airbags expand and push the support surface, so that the support surface presents a U-shaped structure with high left and right sides and low middle when in normal state or under pressure. The shape of the support surface is more in line with the shape of the back of the human head, and the user experience is more comfortable; and the user's head rests on the downward concave part of the support surface, and the head is clamped in the middle by the bulging airbags on both sides, so that the user's head is stably supported by the airbags and is not easy to deflect to the left and right sides, so that the user can maintain a comfortable sitting or lying position. As a result, the headrest body can provide a stable and comfortable support effect for the user's head, which is ergonomic. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant utility model, rather than to limit the utility model. It is also necessary to explain that, for ease of description, only the parts related to the utility model are shown in the accompanying drawings.
[0027] Please refer to the attached Figure 1-9 The embodiment of the present application provides an ergonomic headrest, including a headrest body 1, the headrest body 1 includes a support surface 101 on the front side, the support surface 101 is configured to support the user's head, the inner cavity of the headrest body 1 is divided into left and right parts and is provided with at least one pair of airbags 2, the airbags 2 have switchable inhalation state and deflation state; in the deflation state, the airbags 2 shrink and the support surface 101 tends to be horizontal; in the inhalation state, the airbags 2 expand and push the support surface 101, the support surface 101 presents a concave structure with high left and right sides and low middle, or the support surface 101 presents a concave structure with high left and right sides and low middle when subjected to pressure, and the raised surface of the airbag 2 forms an inclined stopper in the support surface 101.
[0028] Please refer to the attached Figure 5-6 In this embodiment, airbags 2 are arranged on both sides of the inner cavity of the headrest body 1. In the deflated state, the airbags 2 shrink and the support surface 101 tends to be horizontal, so that the headrest body 1 can be used as a conventional pillow; in the inhaled state, the airbags 2 expand and push the support surface 101, so that the support surface 101 presents a U-shaped structure with high left and right sides and low middle when it is normally or under pressure. The shape of the support surface 101 fits the shape of the back of the human head better, and the user experience is more comfortable; and, as shown in the attached Figure 8 As shown, the user's head rests on the downwardly concave portion of the support surface 101, and the head is sandwiched between the bulging airbags 2 on both sides, so that the user's head is stably supported by the airbags 2 and is not easily deflected to the left or right, so that the user can maintain a comfortable sitting or lying position. Therefore, the headrest body 1 can provide a stable and comfortable support effect for the user's head, which is ergonomic.
[0029] Preferably, in addition to the airbag 2, the inner cavity of the headrest body 1 is also filled with PP cotton, which has good elasticity and fluffiness, making the use experience of the headrest body 1 softer and more comfortable. Of course, in other embodiments of the present application, the headrest body 1 can also be filled with down, sponge, etc.
[0030] Please refer to the attached Figure 5-6 In some embodiments of the present application, a plurality of airbags 2 stacked in a vertical direction are provided on either side of the left or right sides of the inner cavity of the headrest body 1 .
[0031] In this embodiment, in the inhaled state, the airbag 2 not only increases in size, but also increases in hardness; therefore, if only one airbag 2 is provided on each of the left and right sides of the headrest body 1, when the airbag 2 expands to a U-shaped structure on the support surface 101, its hardness is also relatively high, which will result in insufficient softness of the headrest body 1 as a whole, and a relatively uncomfortable user experience. Therefore, by providing a plurality of airbags 2 stacked in the vertical direction, compared to providing only one airbag 2, when both expand to the same height, each of the stacked airbags 2 expands less, has a lower hardness, and has a smaller impact on the overall softness of the headrest body 1.
[0032] Please refer to the attached Figure 5-6 In some embodiments of the present application, a plurality of airbags 2 located on either side of the left or right sides of the inner cavity of the headrest body 1 are connected to each other at one end close to the middle of the headrest body 1 to form a whole.
[0033] In this embodiment, the ends of the several airbags 2 near the middle of the headrest body 1 are connected together, so that in the inhaled state, the ends of the several airbags 2 stacked together near the left and right sides of the headrest body 1 squeeze each other and thus stretch out, so that the height of the ends of the several airbags 2 stacked together near the middle of the headrest body 1 is lower than the ends near the two sides of the headrest body 1, and the pushing surfaces of the airbags 2 are inclined from the left and right sides of the headrest body 1 to the middle; so that when there is no pressure, the support surface 101 is supported by the inclined pushing surfaces of the airbags 2 on both sides and is propped up outward, and the surface tends to be horizontal; when the support surface 101 is under pressure, the support surface 101 is recessed downward until the support surface is recessed downward along the inclined pushing surfaces of the airbags 2, presenting a structure with high sides and low middle, which better fits the human head.
[0034] Please refer to the attached Figure 8 In other embodiments of the present application, the airbags 2 on the left and right sides of the headrest body 1 can also be arranged at intervals, leaving a certain gap between the airbags 2 on both sides, so that the support surface 101 located on the gap is not easily stopped by the top surface of the airbag 2 and is more likely to sink, so that no matter whether the airbag 2 is in the inhaled state or the deflated state, the support surface 101 always presents a concave structure with high left and right sides and low middle.
[0035] In some embodiments of the present application, preferably, three airbags 2 stacked in the vertical direction are provided on any one of the left and right sides of the inner cavity of the headrest body 1. This not only ensures the support effect of the headrest body 1, but also prevents the airbag 2 from being too hard in the inhaled state and affecting the softness of the headrest body 1. Of course, in other embodiments of the present application, the number of airbags 2 on any one side of the inner cavity of the headrest body 1 can also be two, four, etc.
[0036] Please refer to the attached Fig. 9 The embodiment of the present application also provides an ergonomic headrest, including a headrest body 1, the headrest body 1 includes a support surface 101 on the front side, the support surface 101 is configured to support the user's head, and the inner cavity of the headrest body 1 is divided into at least one pair of airbags 2 in the upper and lower parts, and the airbags 2 have switchable inhalation state and deflation state; in the deflation state, the airbags 2 shrink and the support surface 101 tends to be horizontal; in the inhalation state, the airbags 2 expand and push the support surface 101, so that the support surface 101 presents a U-shaped structure with high sides and low middle.
[0037] In this embodiment, airbags 2 are arranged on the upper and lower sides of the headrest body 1, so that in the inhaled state, the support surface 101 presents a U-shaped structure with higher upper and lower sides and lower middle. It not only fits the structure of the human head and provides a comfortable user experience, but also when the user's head rests on the downwardly concave part of the support surface 101, the protrusion on the lower side of the support surface 101 can fit and support the user's neck, so that the headrest body 1 can be used as a neck pillow to protect the health of the user's cervical spine.
[0038] Please refer to the attached Figure 1-4 The embodiment of the present application also provides a sofa, including a cushion and an ergonomic headrest as described above, wherein the headrest body 1 is located at the top of the cushion 3, and the cushion 3 also includes a back support portion 310 and a waist support portion 320, and airbags 2 are provided in the back support portion 310 and the waist support portion 320.
[0039] In this embodiment, the back support portion 310 and the lumbar support portion 320 on the cushion 3 are both provided with airbags 2, so that the user can change the hardness and height of the back support portion 310 and the lumbar support portion 320 by adjusting the contraction or expansion of the airbags 2 according to personal preference, and select a suitable state of the cushion 3 to improve the comfort of the sofa.
[0040] Please refer to the attached Figure 1-2 In some embodiments of the present application, the sofa also includes a seat cushion, the seat cushion 4 is configured to support the user's buttocks, and a rotating mechanism is also provided at the bottom end of the back cushion 3 so that the back cushion 3 can rotate forward and backward relative to the seat cushion 4.
