Description
Technical Field
The utility model relates to the technical field of furniture in general, in particular to an ergonomic headrest and a sofa.
Background
The sofa is a common seat in daily life, and people can sit and lie on the sofa to rest and also can watch television, play mobile phones and other entertainment activities while resting. In addition, in order to relax the mind and body and relieve the pressure when sitting, the comfort level of the sofa headrest is required by consumers to be high.
The traditional sofa headrest is generally made of leather or cotton cloth, is filled with flexible materials such as PP cotton and down, is soft and comfortable in use experience, and is also partially provided with an air bag which is additionally arranged inside, and can be controlled to expand or contract through an adjusting switch, so that the softness and hardness degree of the headrest and the height of the headrest are adjusted.
The traditional sofa headrest has better flexibility, but has a single shape, the supporting surface of the headrest is mostly of a horizontal or forward protruding cambered surface structure, even though the shape-changeable air bag headrest is usually provided with only a single air bag in the headrest, the supporting surface of the headrest is of a horizontal or forward protruding cambered surface structure no matter how the air bag expands or contracts, and as shown in figure 7, the supporting surface which protrudes backwards is of a circular arc shape, so that when the head of a user leans against the headrest, the horizontal or forward protruding supporting surface cannot be well attached to the back of the head of the user, the head of the user cannot be stably supported, and is easy to deviate leftwards or rightwards to cause the user to lie and twist, thereby not only bringing poor sitting experience, but also being unfavorable for body health.
Disclosure of Invention
In view of the above-mentioned drawbacks or shortcomings in the prior art, it is desirable to provide an ergonomic headrest and sofa, in which the left and right sides of the inner cavity of the headrest body are provided with air bags, the support surface tends to be horizontal in the deflated state, the headrest body can be used as a conventional pillow, in the inflated state, the air bags push the support surface so that the support surface presents a concave structure with high left and right sides and low middle, the shape of the support surface is more comfortable to use, and the head of the user leans against the position on the support surface, which can be concave downwards, and the head is clamped in the middle by the air bags with raised sides, so that the head is not easy to deflect to the left and right sides. Thus, the headrest body can provide a stable and comfortable supporting effect for the head of a user, and accords with ergonomics.
The effect of the utility model is realized as follows:
In a first aspect, the application provides an ergonomic headrest comprising a headrest body having a front support surface configured to support a user's head, the headrest body having an inner cavity having a left and right spaced apart at least one pair of air cells having a switchable air-intake condition and an air-discharge condition, the air cells being contracted such that the support surface tends to be horizontal, the air cells expanding and pushing the support surface in the air-intake condition, the support surface exhibiting a concave configuration with a high middle and a low side on the left and right sides or the support surface exhibiting a concave configuration with a high middle and a low side on the left and right sides when subjected to pressure, and a jacking surface of the air cells forming a tilt stop in the support surface.
Further, any one of the left side and the right side of the inner cavity of the headrest body is provided with a plurality of air bags stacked along the vertical direction. The single air bag has smaller expansion degree and lower hardness in the air suction state, and has smaller influence on the softness of the whole headrest body.
Further, the two air bags are arranged on any one of the left side and the right side of the inner cavity of the headrest body, and one ends of the plurality of air bags, which are close to the middle part of the headrest body, are mutually connected into a whole. Under the state of air suction, the end parts of the air bag, which are close to the left side and the right side of the headrest body, are mutually extruded so as to stretch out, the surface of the air bag tends to be horizontal when the supporting surface is not pressed, and the supporting surface is downwards sunken along the inclined pushing surface of the air bag when the air bag is pressed, so that the shape of the air bag is more fit with the head of a human body.
Further, three airbags stacked in the vertical direction are arranged on any one of the left side and the right side of the inner cavity of the headrest body. The supporting effect of the headrest body is guaranteed, and the influence of the air bag over-hardness on the softness of the headrest body in the air suction state can be avoided.
The application provides an ergonomic headrest, which comprises a headrest body, wherein the headrest body comprises a supporting surface on the front side, the supporting surface is configured to support the head of a user, at least one pair of air bags are arranged in an upper-lower separation mode in an inner cavity of the headrest body, the air bags are in a switchable air suction state and an air discharge state, the air bags are contracted in the air discharge state, the supporting surface tends to be horizontal, and in the air suction state, the air bags are expanded and push the supporting surface, so that the supporting surface is in a U-shaped structure with the upper side, the lower side, the middle side and the lower side. When the head of a user leans against the downward concave part on the supporting surface, the protrusions on the lower side of the supporting surface can be attached to and support the neck of the user, so that the head rest body can be used as a neck rest to protect the cervical vertebra health of the user.
In a third aspect, the application provides a sofa comprising a cushion and an ergonomic headrest, wherein the headrest body is positioned at the top end of the cushion, the cushion further comprises a back support portion and a waist support portion, and air bags are arranged in the back support portion and the waist support portion. The user can change the softness and hardness degree and the height of the back support part and the waist support part by adjusting the contraction or the expansion of the air bag according to personal preference, and the proper back cushion state is selected, so that the comfort level of the sofa is improved.
Further, the sofa further comprises a cushion, the cushion is configured to support buttocks of a user, and a rotating mechanism is further arranged at the bottom end of the cushion, so that the cushion can rotate back and forth relative to the cushion. Make no matter the user is in sitting up posture or lying down posture, the cushion all can be adjusted to laminating user's back for reliable support, make the practicality better.
According to the ergonomic headrest and sofa provided by the application, the air bags are arranged on the left side and the right side of the inner cavity of the headrest body, the air bags shrink in the deflation state, the supporting surface tends to be horizontal, the headrest body can be used as a conventional pillow, in the inspiration state, the air bags expand and push the supporting surface, the supporting surface is in a U-shaped structure with the high left side and the low middle when the supporting surface is normal or pressed, the shape of the supporting surface is more fit with the shape of the hindbrain of a human body, the use experience is more comfortable, moreover, the head of a user leans against the downwards sunken part on the supporting surface, the head of the user is clamped in the middle by the air bags with the two bulged sides, the head of the user is stably supported by the air bags, and the left side and the right side of the supporting surface are not easy to deflect, so that the user can keep a comfortable sitting posture or lying posture. Thus, the headrest body can provide a stable and comfortable supporting effect for the head of a user, and accords with ergonomics.
