Abstract:
A stroller, comprising:a supporting frame, a seat frame supported by said supporting frame, and a handle frame having two construction bars upwardly extended from said supporting frame wherein said seat frame comprises a seat support horizontally supported by said supporting frame and a back support upwardly extended from said seat support; and an adjustable seat back arrangement, which comprises: two side supporting units sidewardly extended from two vertical sides of said back support to said two construction bars respectively for folding said back support between an upright position and a fully extended position, wherein in said upright position, said back support is vertically extended from said seat support, and in said fully extended position, said back support is inclinedly extended from said seat support with a maximum inclined angle between said back support and said seat support; and at least two inclination locking means for selectively locking said back support to said construction bars respectively, wherein each of said inclination locking means comprises: a first locking element and a second locking element provided between said back support and said respective construction bar, wherein said first locking element is affixed on said respective side supporting unit adjacent to said back support and said corresponding second locking element is affixed on said side supporting unit adjacent to said construction bar; and a sliding locker which is adapted to lock up said first and second locking elements and selectively adjust a distance between said back support and said respective construction bar so as to adjust an inclined angle between said back support and said seat support, wherein said sliding locker normally locks up two bottom ends of said first and second locking elements and is arranged in such a manner that when said sliding locker is slid upwardly, said first and second locking elements are fittedly engaged with each other, so as to reduce said width between said back support and said construction bars and when said sliding locker is slid downwardly, said first and second locking elements are disengaged with each other, so as to lengthen said width between said back support and said construction bars.
