New description: 【New technical field of the art】 This creation is an improved engineering chair, especially a kind of suitable support for the cervical vertebra, which can avoid neck sore when riding. ^Previous technique if seat Usually, it is composed of a seat, a chair and a (4). The pad is placed on the seat, and the back of the chair is connected to the seat cushion at an appropriate oblique angle. The user can sit on the seat cushion. , leaning against the back of the chair. Month ^ However, the seat back of the conventional seat can not effectively support the vertebrae', resulting in poor head money when riding, long time county sitting or coughing: sleeping on the seat, will force the peripheral nerves of the cervical vertebrae, causing the neck ;: Severe soreness, and affect the development of the central nervous system. [New content] The creators have in view of the shortcomings of the prior art chairs used in the prior art, and are based on their experience in the manufacture of various chairs and the accumulation of technology, and have studied the various solutions in a way that is lacking in the study of the lectures. After the 'final development and design of a new and improved engineering chair creation of this creation' in order to eliminate the lack of prior art. One of the purposes of this creation is to provide an improved engineering chair that allows the chair to support the atlas and to avoid the pain of the M343433 in the neck. According to the above purpose, the engineering chair of the present invention comprises a seat, a seat cushion and a seat back, wherein the seat has front and rear legs; the seat cushion is located above the seat; and the seat back is provided Behind the seat, the supporting force of the cushion body on the back of the chair extends from the lower end of the seat back to the upper end, so that the compressive stress of the driven waist disperses and supports the back of the human body, and the seat back has a convex position at the position of the corresponding cervical vertebra. The support pad body is for supporting the human body after the cervical vertebra, and the chair back is provided with a head pad above the support pad body, the head pad is provided with a plurality of equidistantly arranged concave portions for supporting the rear of the human body head, and The lower end is close to the waist position of the human body as a center point, and the two sides of the support pad body are fan-shaped from the upper end to the lower end and gradually inclined toward the center point, and the recessed portions are also fan-shaped from the upper end toward the lower end and gradually inclined toward the center point, so that The compressive stress of the dry waist disperses and supports the design of the back of the human body, the support pad of the cervical vertebrae and the head cushion. The back of the chair can properly support the cervical vertebra, so as to avoid the soreness of the neck during long time riding, and at the same time, through the support Thereof, each depressed portion 5 is inclined and the count of the sector, so that regardless of the user how to change the posture, can appropriately support the vertebral head, to avoid poor posture neck pain is generated. In order to make the examination committee members able to further understand and understand the purpose, shape, structure and function of the creation, the following examples are combined with the drawings, and the details are as follows: [Embodiment] This creation is related to a kind of " The modified engineering chair, please refer to the figures 1 and 3, the engineering chair of the creation, which includes a chair M343433 f 20, a factory chair cushion 30 and a seat back 4〇, wherein the seat 2〇The rear holding legs 21, 22; the seat cushion 3〇 is located above the seat 2〇; and the chair 2〇: behind the chair 20, the back of the seat back 4〇 is the back of the chair The lower end is fan-shaped and extends upwards to support the back of the human body 50 and the back of the chair 4. Corresponding to: the upper part has a protruding support body 42 for supporting the human body 50, and then the cervical vertebra-5-back chair back 40 is provided with a head 43 above the support pad body 42, and the head pad 43 is provided with a plurality of equally spaced The recessed portion 44 is for supporting the rear of the head 52 of the human body 50, and further, the lower end of the seat back 4 is close to the waist position of the human body, and the two sides of the branch body 42 are fan-shaped from the upper end to the lower end and gradually toward the center. The point is inclined, and each of the depressed portions 44 is fan-shaped from the upper end toward the lower end and gradually inclined toward the center point. By the composition of the above components, please refer to the figures 2, 3, and 4, when riding, the compressive stress of the waist can be dissipated through the back of the chair 4G to support the back of the human body 50, and the support body 42 supports the human body 5〇 rear cervical vertebra 51 And the recessed portion 44 of the head pad 43 supports the design of the human body 5 〇 head 52, and the back of the squat can properly support the cervical vertebra, so that the neck pain can be avoided when riding for a long time (when sleeping on the creative engineering chair 10) At the same time, the over-rotating pad body 42 and the recessed portions 44 have a fan-shaped slanting design, so that no matter how the user changes the sitting posture (or sleeping posture), the cervical vertebra can be properly supported to avoid neck pain caused by poor sitting posture. Referring to Figures 3 and 4, the width of the groove width of the depressed portion of the head pad 43 may be greater than 2/3 of the width of the human body. In this creation, the supporting force of the back 40 of the chair back is extended from the lower end of the seat back to the upper end, and the lower end is located on the spine of the waist of the human body, that is, the center of the fan is at the caudal vertebra, and the chair is made. The back 4〇 has the stress of the waist of the M343433 to disperse and support the human body 50 back to the human body, to avoid the poor posture due to poor posture, and the pain caused by the neck is severely sore, which affects the central nervous system. Figure 1 shows the chair It can be a foam pad, which makes the user feel soft and comfortable when riding. _Please refer to Fig. 1, the pad body 41, the support pad body 42, and the pad 43 can be - foam pads, and the 俾(4) can feel soft and comfortable when riding. In summary, the improved engineering chair of this creation does have an unprecedented innovative structure. It has not been found in any publications, and there is no similar product in the face. Therefore, its novelty should be j consideration. In addition, the unique features and functions of this creation are far from comparable, so it is indeed more progressive than the application, and it meets the requirements of the application requirements for new patents in China's patent law. The above description is only the best embodiment of the present invention, but the structural features of the present creation are not limited thereto, and any change or modification that can be easily considered by the skilled person in the field of creation can be covered. In the following patent scope of this case. M343433 [Simple description of the drawing] The first picture shows the three-dimensional appearance of the creative engineering chair.
