Safety belt retractor with external children protection latch mechanism

Abstract

The invention belongs to the technical field of automobile safety belt retractors, and in particular relates to a safety belt retractor with an external children protection latch mechanism. The safety belt retractor with the external children protection latch mechanism comprises an urgent latch type safety belt, a children protection eccentric wheel, a children protection reset spring, a triggering torsional spring and a children protection triggering gear. The safety belt retractor with the external children protection latch mechanism is characterized in that the external children protection latch mechanism is spliced on an outer cover of the urgent latch type safety belt; the external children protection latch mechanism comprises a children protection eccentric wheel, a children protection reset spring, a children protection triggering plate, a children protection triggering claw, a children protection triggering gear, a triggering torsional spring and a children protection cover. Compared with the prior art, the invention has compact structure, ensures that the external children protection latch mechanism is conveniently spliced without changing the original safety belt structure, saves the reformation cost, effectively protects safety of children on an automobile, realizes that an automatic latch type retractor and the urgent latch type retractor can be freely switched and solves the problem that the ordinary urgent latch type safety belt can not be mounted in a reversible seat.

Description

[Technical field] [0001] The present invention relates to the technical field of automobile seat belt retractors, specifically a seat belt retractor with an external child protection locking mechanism.
