Child safety seat having side protection function

Abstract

The invention discloses a child safety seat having a side protection function, and relates to the field of child safety seats. Buffer and energy absorption during a collision are facilitated through adding spring dampers to a base, a backrest, a headrest and the like of a child safety seat, and thus harm to the child body caused by the collision is decreased. Meanwhile, practicability is provided through the optimization on the unlocking of a FIX, a pedal and a safety belt assembly of the seat; and as an anti-spatter assembly is also added, and harm to the child from spatter matters during the collision is avoided.

Description

technical field [0001] The invention relates to the field of child safety seats, in particular to a child safety seat with a side protection function. Background technique [0002] The progress and development of human civilization and science and technology have enabled us to have a variety of vehicles for different purposes, operating in different fields at different speeds. When accidental accidents of these vehicles collide, the occupants will be in a mechanical shock load environment, and various tissues of the human body will produce corresponding biomechanical responses under the action of inertial force and contact force. Once the human tissue exceeds the recoverable limit, it will lead to the destruction of chemical tissue or the damage, decay or loss of normal physiological function, which will cause permanent damage, such as fracture, tendon and ligament rupture, organ rupture, bruising and bleeding, and brain damage. Concussion causes intracranial hemorrhage, fa...

Problems solved by technology

[0006] 3. Child safety seat front body protection safety protection technology: child safety front body protection technology: this technology uses a large-area blocking displacement method, so that the impact force of the human body acts on a large-area cushion to reduce unit pressure and head displacement It can act on the buffer pad of the device to play the role of head buffer to prevent cervical spine and cervical muscles and ligaments from being damaged. However, this method makes the human chest and abdomen bear force but is not good for the organs, and because there is no upward force constraint, the human body is moved from the front Accidents caused by jumping out from body restraints

This protection device can protect the life of the driver and occupant within the relative speed range, but it cannot protect the occupant from injury. When the inertial force of the human body is bound to the limit by the seat belt, the huge inertial force may cause fractures of the clavicle, sternum, and scapula. Once the airbag is opened, its speed can reach 300Km / h, which will have a great impact on the human head. Although it is not fatal, its biological reaction will also bring different degrees of harm to people, such as concussion, fainting or even intracranial hemorrhage.

[0009] Based on the above-mentioned existing safety protection device technology, its technical feature is to limit the displacement of personnel to prevent direct collision between the human body and the vehicle components, and to use cushioning materials to absorb the impact energy, and to play a certain protective role within a certain speed range. range, coupled with individual differences, cannot guarantee occupant safety
