Infant bidirectional basket type safety seat with tension springs for buffering

Abstract

The invention relates to a basket type child safety seat, in particular to an infant bidirectional basket type safety seat with tension springs for buffering. Springs for damping are added in a base, a backrest, a headrest and the like of the infant safety seat so as to facilitate buffering and energy absorption during collision, and bodily injury to children due to collision is reduced. Meanwhile, a basket unlocking component, a handle rotation limiting component, a footrest component and a safety belt component of the seat are optimized to supply practicability; an anti-splashing component is added to avoid injury to children due to splashing materials during collision.

Description

Technical field [0001] The invention relates to a child safety seat, in particular to a two-way basket-carrying safety seat for infants. 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 in different ways and speeds. When these vehicles accidentally collide, the occupants will be in a mechanical shock load environment. Under the action of inertial force and contact force, various tissues of the human body will produce corresponding biomechanical responses. Once the human tissue exceeds the recoverable limit, it will cause the destruction of the destructive tissues or the damage to normal physiological functions, decay or loss, which will cause permanent damage, such as fractures, rupture of tendons and ligaments, rupture of organs, bruises and bleeding, and brain Concussion causes intracranial hemorrhage, fainting, obstruct...

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
