Abstract

A belt assembly is arranged on a back side of a backrest of a baby carriage, so that the angle of inclination of the backrest may be changed by adjusting of the length of the belt assembly. The belt assembly includes a first belt, a second belt, and a buckle which is attached to an end of the first belt and which has the second belt passing therethrough. The second belt has on its first major surface a plurality of engaging cavities. The buckle holds an operating member, which is cross-directionally or laterally movable across the second belt, and which is urged by a spring to move downwardly. The operating member is provided with engaging projections, which can selectively engage the engaging cavities. The length of the belt assembly is fixed when the engaging projections engage the engaging cavities, while the length of the belt assembly is rendered changeable when the former disengage from the latter. Thus, an adjusted length of the belt assembly can be reliably maintained by engagement of the engaging projections in the engaging cavaties.

Dependent claims

A baby carriage comprising:

a seat having a seat portion and a backrest portion upwardly extending from a rear end of said seat portion so that said backrest portion has an angle of inclination that is changeable;
first and second fixed members positioned at two sides of said seat respectively;
and
a belt assembly arranged on a back side of said backrest portion in supporting contact with said backrest portion, wherein said belt assembly has a length that is adjustable for changing said angle of inclination of said backrest portion;
wherein said belt assembly includes a first flexible belt having first and second ends wherein said first end is coupled to said first fixed member, a second flexible belt having first and second ends wherein said first end is coupled to said second fixed member, and a buckle coupled to said second end of said first belt wherein said buckle has a belt passage through which said second belt can be passed,
wherein said second belt has a first major surface and longitudinal edges along said surface and a recessed serrated step portion is formed as a recess in said first major surface, and a plurality of engaging cavities are formed in said serrated step portion longitudinally along said second belt between said longitudinal edges,
wherein said buckle includes an operating member movably held in said buckle to extend across said belt passage on said first major surface of said second belt, wherein said operating member is laterally slidable across said second belt, and said buckle further includes a spring arranged to urge said operating member to move in a first direction,
and wherein said operating member has an engaging projection that projects into said recessed serrated step portion and is adapted to move within said serrated step portion to engage with any one of said plurality of engaging cavities upon movement of said operating member under urging of said spring in said first direction, and said operating member further includes a press operating part projecting from said buckle and adapted to be pressed to drive said operating member in a second direction.

5 more elements

A length-adjustable belt assembly on a baby carriage with a frame with first and second components, said belt assembly connected between the first component and the second component, said belt assembly comprising a first flexible belt having a fixed end adapted to be connected to the first component and a free end, a second flexible belt having a fixed end adapted to be connected to the second component and a free end, and a buckle connected to said free end of said first belt, wherein said second belt has first and second major surfaces and longitudinal edges along said surface, said first major surface has a recessed engagement groove formed therein to extend in a longitudinal direction of said second belt, said engagement groove includes serrated steps and engagement cavities distributed longitudinally along said recessed engagement groove, said buckle comprises a buckle body having a belt passage adapted to receive said second belt passing through said belt passage, and said buckle further comprises an operating member movably held in said buckle body to be slidable between an engagement position and a disengagement position in a lateral direction across said first major surface of said second belt in said belt passage, an engaging projection projecting from said operating member and reaching into said recessed engagement groove while being adapted to move within said recessed engagement groove to engage any one of said engagement cavities when said operating member is moved into said engagement position and to disengage from said engagement cavities when said operating member is moved into said disengagement position, and a spring arranged to apply an urging force to urge said operating member toward said engaging position.
