Abstract

An ergonomic headrest for an office chair is provided. The headrest includes a pillowing member. The pillowing member includes a moderately bulging upper pillowing side and a substantially convex cervical pillowing side and has a slightly depressed occipital pillowing side formed therebetween. A resilient element is disposed behind the headrest for abutting against the headrest resiliently. With the sitter's head resting on the headrest, the sitter's neck and occiput rest on the cervical pillowing side and the occipital pillowing side exactly. Hence, the sitter's neck and occiput can rest on the ergonomic headrest which contours thereto. This, coupled with the resilience and ergonomic contour of the headrest, enables the sitter's head to receive ergonomic and comfortable support.

Description

FIELD OF THE INVENTION

The present invention relates to a headrest for an office chair. The head rest comprises a moderately bulging upper pillowing side and a substantially convex cervical pillowing side and has a slightly depressed occipital pillowing side formed between the upper pillowing side and the cervical pillowing side, such that the headrest contours to a sitter's neck and occiput, thereby allowing the neck and the occiput to rest on the headrest comfortably.

BACKGROUND OF THE INVENTION

Office work usually accounts for the majority of the daytime when it comes to office workers nowadays. In view of this, a comfortable office chair plays an important role in relieving work-related stress, preventing overstrain, and relaxing the mind. A conventional office chair comprises a headrest, armrests, and a chair back. The headrest is height-adjustable by being moved upward or downward. The height of the armrests can be properly adjusted so that the armrests will support part of the weight of the sitter's head and arms through the armrests if the sitter's arms are resting on the armrests. The chair back reclines slightly to support the sitter's back properly. The conventional office chair may even have an ergonomic waist rest for supporting the sitter's waist efficiently enough to spread out the pressure exerted upon the upper half of the sitter's body. Hence, the conventional office chair is suitable for sitters who sit for a long time.
Although the conventional headrest is height-adjustable to support the sitter's head and is equipped with a curved supporting side and a resilient yet soft pillow surface for supporting the sitter's head gently and comfortably, it has its own drawbacks. The conventional headrest does not support the sitter's neck, nor does its pillow surface contour to the sitter's head. As a result, the conventional headrest for an office chair does not meet ergonomic requirements and thus does not give ergonomic support to the sitter's head.

SUMMARY OF THE INVENTION

To overcome the aforesaid drawbacks of the conventional headrest for an office chair, that is, incapability of providing ergonomic support, the present invention provides an ergonomic headrest for an office chair. The ergonomic headrest comprises a pillow body. The pillow body has a bulging upper pillowing side, a convex cervical pillowing side, and a slightly depressed occipital pillowing side formed between the upper pillowing side and the cervical pillowing side. Hence, the pillowing sides of the ergonomic headrest together contour to an average sitter's head, thereby allowing the sitter's head to rest on the headrest in comfort.
The technical solution proposed by the present invention is as follows: the pillow body of the headrest has a pillowing member; the pillowing member further comprises a bulging upper pillowing side and a convex cervical pillowing side; and the slightly depressed occipital pillowing side is formed between the upper pillowing side and the cervical pillowing side.
Regarding the ergonomic headrest for an office chair according to the present invention, the pillowing member of the pillow body is fixed to a pillowing base, and the pillowing base is fixed to a pillow body base.
Regarding the ergonomic headrest for an office chair according to the present invention, the pillow body comprises an upper pillow body for forming the pillowing member on the upper pillowing side and a lower pillow body for forming the pillowing member on the cervical pillowing side. The pillowing member of the upper and lower pillow bodies is fixed to upper and lower pillowing bases, respectively. Then, the upper and lower pillowing bases are fixed to the pillow body base.
Regarding the ergonomic headrest for an office chair according to the present invention, an upper end on the back of the headrest is pivotally coupled to an upper end of a post, and a resilient element is disposed between the post and a lower end on the back of the headrest.
Regarding the ergonomic headrest for an office chair according to the present invention, the pillowing member is formed from a net.
Regarding the ergonomic headrest for an office chair according to the present invention, the pillowing member is formed from a pad.
Accordingly, the pillowing member of the headrest of the present invention allows a sitter's neck to rest on the cervical pillowing side exactly and allows the sitter's occiput to rest on the occipital pillowing side exactly. This technical feature, coupled with the resilience and ergonomic contour of the headrest, enables the sitter's head to receive ergonomic support in comfort.

DETAILED DESCRIPTION OF THE INVENTION

Referring to FIGS. 1, 2, 3, a headrest of the present invention comprises a pillow body 1 and a pillow body base 2 to which the pillow body 1 is fixed. The pillow body 1 further comprises a pillowing member 11 and a pillowing base 12 on which the pillowing member 11 is disposed. The pillow body 1 is fixed to the pillow body base 2 by means of the pillowing base 12. As shown in the drawings, the pillowing member 11 is formed from a net or a solid foam pad, and the pillowing member 11 comprises a moderately bulging upper pillowing side 111 above and a substantially convex cervical pillowing side 112 below. A depressed occipital pillowing side 113 that contours to an average sitter's occiput is formed between the upper pillowing side 111 and the cervical pillowing side 112.
A pivotally fixing member 21 is disposed at an upper end on the back of the pillow body base 2. The pivotally fixing member 21 is pivotally coupled to a pivotally fixing portion 31 disposed at an upper end of a post 3. An inverted U-shaped resilient element 4 is fixed in place between the post 3 and a lower end on the back of the pillow body base 2. Hence, the sitter's head and neck can rest on the lower end of the headrest due to the resilience thereof.
With the sitter's head resting on the headrest, the sitter's neck rests on the cervical pillowing side 112 exactly and the sitter's occiput rests on the occipital pillowing side 113 exactly; hence, the sitter's neck and occiput can rest on the ergonomic headrest which contours thereto. This technical feature, coupled with the resilience and ergonomic contour of the headrest, enables the sitter's head to receive ergonomic and comfortable support, reduces pressure exerted upon the sitter's head, and relieves discomfort.
Furthermore, although the pillow body 1 is a unitary structure, the pillow body 1 can be otherwise designed in a way shown in FIG. 4. As shown in FIG. 4, the pillow body 1 comprises an upper pillow body 1 a and a lower pillow body 1 b. The upper pillow body 1 a forms the pillowing member 11 on the upper pillowing side 111, such that the pillowing member 11 is disposed on an upper pillowing base 12 a. The lower pillow body 1 b forms the pillowing member 11 on the cervical pillowing side 112, such that the pillowing member 11 is disposed on a lower pillowing base 12 b. As a result, the upper and lower pillow bodies 1 a, 1 b are fixed to the pillow body base 2 by means of the upper and lower pillowing bases 12 a, 12 b; meanwhile, the occipital pillowing side 113 is formed between the upper and lower pillow bodies 1 a, 1 b. The reason why the pillow body 1 is divided into the upper and lower pillow bodies 1 a, 1 b is that each of the upper and lower pillow bodies 1 a, 1 b can be easily changed when dirtied or damaged.
