Abstract
The present invention relates to a seat belt with the functions of absorption of energy and control. The seat belt comprises a vehicle seat belt and an energy absorber composed of an energy absorption pipe, an extrusion die block and an energy transmission piece, wherein an extrusion interface fixed in a vehicle is sheathed with the front part of the energy absorption pipe, the energy transmission piece is connected with the energy absorption pipe, and the other end of the energy transmission piece is connected with the lock catch socket or a retractor or a fixing seat with a buckle. When vehicles are in crash, human bodies move forwards because of inertia effect, and seat belts move forwards along with human bodies. When the vehicle speed is overhigh, the energy absorption pipe overcomes the resistance of the extrusion interface and can be deformed, and the kinetic energy of human bodies is converted into work required by the deformation of the energy absorption pipe. Thereby, the functions of reduction of the kinetic energy of human bodies and protection of passengers can be reached.
Description
Technical field
The present invention relates to a kind of car belt, especially a kind of when automobile has an accident, safety strap that can the absorption portion collision energy.
Technical background
Guarantee that traffic safety has become the problem that human society is very paid close attention to.People have taked multiple safety measure for this reason, and automobile safety seat belt is exactly wherein a kind of.Existing safety strap mainly is made up of taking-up device, guide, snap close plug-in unit, snap close socket, bracelet permanent seat and belt strap.This safety strap can play the actv. effect of contraction to the occupant when auto against, the protection occupant safety.But safety strap itself does not have endergonic effect, when automobile bumps, safety strap, particularly pretension safety strap constrain in the human body upper body on the seat tightly, and people's head still travels forward with original moving velocity drive neck under action of inertia, and then makes people's head, neck injuries.In U.S. Pat 5487562 and US 5971489, relevant safety strap is described.But their weak point is complex structure, cost height, function singleness.
Summary of the invention
