Protection top unit loading/unloading mechanism, seat device for child and two-wheel vehicle

Abstract

The present invention provides a protection top unit loading / unloading mechanism, a seat device for child and a two-wheel vehicle, wherein the protection top unit body can be unloaded from a backrest thereby improving operability and appearance. The protection top unit comprises a front side supporting component and a back side supporting component which can slidably support the supporting legs of the protection top in a vertical direction. A backrest part of a seat device body for child is provided with a left through hole and a right through hole (34) which are in a pair, and a through hole (37). At a state that a hook-shaped part of a mounting component is jointed with an upper end of the front side supporting component, a clamping part of the mounting component strides over an upper part of the backrest and clamps the backrest between a front part and the front side supporting component. Bolts pass through the through holes (34) of the backrest from the front side of the mounting component and are connected with the nuts at the back side of the front side supporting component for fixing. Therefore, the protection top unit can be firmly fixed on the backrest.

Description

technical field [0001] The present invention relates to a roof guard unit attachment and detachment mechanism, a child seat device having the roof guard unit attachment and detachment mechanism, and a two-wheeled vehicle. Background technique [0002] Conventionally, among child seat devices mounted on a bicycle or the like, there is known a child seat device having a height adjusting device for sliding and fixing a headrest to a predetermined height. [0003] Patent Document 1 below discloses a structure in which a holding tube protruding rearward is provided on the back surface of the backrest provided on the main body of the child seat, and the supporting legs provided at the lower part of the headrest Insert the headrest into the holding tube, engage the engaging protrusions installed in the holding tube with the concave-convex rows of the supporting legs, and fix the headrest to the holding tube at a predetermined height with the connector. [0004] Patent Document 2 b...

Problems solved by technology

Therefore, the bearing portion and the pair of clips become redundant components, which deteriorates the operability and appearance of the child seat device.

[0009] On the other hand, if a structure that does not have a holding cylinder or a bearing portion and a pair of clips is made with a specification that does not install a headrest, then there is a difference between the specification that the headrest is installed and the specification that does not install the headrest. A different mold is required for the seat body, which increases manufacturing costs
