Abstract

The utility model provides a car seat for protecting a vertebral column. The car seat comprises a seat back and a seat surface, wherein a recessed groove is arranged at the positions of the seat back and the seat surface, corresponding to the vertebral column of a human body. When the seat back and the seat surface are collided by external forces, the condition that the vertebral column of the human body is directly collided by the seat back and the seat surface can be avoided through the groove, and the vertebral column of the human body is protected; in one embodiment of the utility model, the car seat further comprises a plurality of viscous elastomers arranged on the seat back or the seat surface; the viscous elastomers are symmetrically located on the vertebral column of the human body and are capable of assisting muscles at two sides of the vertebral column in protecting the vertebral column, thus the vertebral column is unlikely to be directly collided by an external force, and the viscous elastomers have the effects of buffering disperse pressures.

Description

The automotive seat of protection vertebra

Technical field

The utility model is the structure of relevant a kind of automotive seat; a kind of being applied in the various vehicleses (Vehicle) such as automobile (car), Recreational Vehicle (RV), truck (truck), bus (Bus), container car (Container trucks) particularly is with the structure of the automotive seat of the vertebra that reaches the protection human body.

Background technology

Automobile is one of modern's important vehicle of riding instead of walk, and many people can take advantage of the main traffic instrument of seat every day especially.The required position of the having a rest when radical function of automotive seat is to provide the passenger to ride in an automobile; based on security needs; automaker or automotive seat makers also take much count of the safety of automotive seat, and the protection effect that provides for the passenger of automotive seat.

in the automobile safety accident of major part, the major cause that damages for the passenger is that human body is subject to huge external force collision or collision, and then human body is caused the injury of physics, and being produced the situation of clashing into or colliding, human body comprises that human body collides object, and object directly collides two kinds of situations of human body, front a kind of situation can be avoided by the mode that safety strap is fixed in automotive seat with the passenger, known protected mode for rear a kind of situation also has many known technology to realize, the safety air bag of automobile for example, have the automotive seat of buffering effect and the headrest of automotive seat, particularly the headrest of automotive seat can also provide the support of cervical vertebra, can when suffering the rear external force collision, automobile protect cervical vertebra to avoid being subject to serious injury.

The structure of the vertebra of human body as shown in Figure 1, picture " S " type of looking from the side, comprise 7 joint cervical vertebras, 12 joint thoracic vertebraes and 5 joint lumbar vertebraes, each of rumpbone and tail bone is arranged below lumbar vertebrae, vertebra is a kind of similar cylindrical structure, be connected in medulla oblongata, extended to the position of second lumbar vertebra by foramen magnum, it is a thick nerve tract, the transmission of information back and forth at brain and health other positions, it is joined at base portion and the brain of skull, along the passage that is formed by vertebral foramen to downward-extension.Muscle, blood vessel and nerve are positioned at backbone front and both sides; The radical function of vertebra comprises: support body weight; Conduction gravity is to keep balance; Make brain transmit information with protection spinal cord (Spinal Cord) and nerve root (Nerve Root), or receive information, and make nervous system protected.

as shown in Figure 2, under general situation, when the passenger is sitting in automotive seat, the vertebra 40 of human body dorsal part can be absorbed between the muscle of back 41 of both sides, the chair back 70 preferentially contacts with the muscle of back 41 of the both sides of vertebra 40, the strength at back is supported by the muscle of back 41 of the both sides of vertebra 40, when posture changes, particularly vehicle drive is when stretching out both arms steer direction dish (as shown in Figure 3), the muscle of back 41 that originally is positioned at the both sides of vertebra 40 can stretch to both sides, this moment the back vertebra 40 can seem comparatively outstanding even can with the Surface Contact of the chair back 70, in this case, if automobile is subject to shock or the collision of huge power external force, the chair back 70 just causes very large shock or collision to the vertebra 40 at the back of human body possibly, and directly vertebra 40 is damaged.
