Description
Technical field
This utility model is related to wheelchair technical field, more particularly, to a kind of seats back inclining mechanism.
Background technology
Referring to shown in accompanying drawing 5 and accompanying drawing 6, for Wheelchair structure more typically at present, the rotation of its seat frame of the wheelchair of this structure
Central point is all being taken below face, remote with the central point distance of occupant, amplitude l moved after occupant's focus point during adjustment angle
(distance versus with trailing wheel central shaft) are very big, are so easy to the dangerous situation of hypsokinesis, have serious potential safety hazard.
Content of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of seat 1 center of rotation close to human body
Center of gravity, thus prevent the seats back inclining mechanism that wheelchair is toppled over backward.
In order to realize object above, the technical solution adopted in the utility model is:
A kind of seats back inclining mechanism, including seat, for supporting the seat support of seat bottom and being used for before connection
The wheel carrier of trailing wheel, also includes arc guide rail, back-up roller wheel, the first telescopic supporting rod and the second telescopic supporting rod, described circular arc
Guide rail is fixedly connected on seat support bottom, and the center of circle of its circular arc is located above seat；Described back-up roller wheel is arranged at wheel
Frame top, for supporting arc guide rail bottom；The two ends of described first telescopic supporting rod are respectively articulated with wheel carrier and arc guide rail
End, the two ends of described second telescopic supporting rod are respectively articulated with seat back and arc guide rail rear end.
Further, described wheel carrier top is additionally provided with internal trolley, the periphery of described internal trolley and described arc guide rail upper table
Face is mutually close to.
The beneficial effects of the utility model are: a kind of seats back inclining mechanism of the present utility model, its seat support bottom
Portion is provided with arc guide rail, and is provided with the back-up roller wheel for supporting arc guide rail bottom on wheel carrier top.When chair tilting hour wheel
Frame can be rotated along the center of circle of arc guide rail with seat support, because the center of circle of arc guide rail is located above seats, with biography
The center of rotation of steerage chair is compared closer to gravity center of human body, so that during wheelchair hypsokinesis gravity center of human body is in the horizontal direction
Displacement less, it is to avoid gravity center of human body excessively leads to wheelchair to be toppled over backward rearward, improve wheelchair safety.

Specific embodiment
In conjunction with the drawings and specific embodiments, to this utility model, technical scheme required for protection is made further specifically
Bright.
Referring to accompanying drawing 1 to shown in accompanying drawing 4, a kind of seats back inclining mechanism of the present embodiment, including seat 1, for propping up
Support seat 1 bottom seat support 2 and for connect front and back wheel wheel carrier 3 it is characterised in that: also include arc guide rail 4,
Support roller 5, the first telescopic supporting rod 6 and the second telescopic supporting rod 7, described arc guide rail 4 is fixedly connected on seat support 2 bottom
Portion, and the center of circle of its circular arc is above seat 1；Described back-up roller wheel 5 is arranged at wheel carrier 3 top, for supporting circular arc to lead
Rail 4 bottom, in the present embodiment, described wheel carrier 3 top is additionally provided with internal trolley 8, the periphery of described internal trolley 8 and described circular arc
Guide rail 4 upper surface is mutually close to, and is cooperated by internal trolley 8 and back-up roller wheel 5, can prevent arc guide rail 4 in vertical direction
Upper swing.The two ends of described first telescopic supporting rod 6 are respectively articulated with wheel carrier 3 and the end of arc guide rail 4, and described second stretches
The two ends of contracting support bar 7 are respectively articulated with seat 1 back and arc guide rail 4 rear end.
A kind of seats back inclining mechanism of the present embodiment, its seat support 2 bottom is provided with arc guide rail 4, and in wheel carrier 3
Top is provided with the back-up roller wheel 5 for supporting arc guide rail 4 bottom.When seat 1 hypsokinesis, wheel carrier 3 and seat support 2 can be along
The center of circle of arc guide rail 4 rotates, and is located at the center of rotation above seats, with traditional push chairs due to the center of circle of arc guide rail 4
Compare closer to gravity center of human body, so that gravity center of human body mobile range l in the horizontal direction is less during wheelchair hypsokinesis,
Avoid gravity center of human body excessively to lead to wheelchair to be toppled over backward rearward, improve the safety of wheelchair.
The embodiment of the above is only preferred embodiment of the present utility model, and not this utility model is done with any form
On restriction.Any those of ordinary skill in the art, without departing under technical solutions of the utility model ambit, all can profit
With the technology contents of the disclosure above, technical solutions of the utility model are made with more possible variations and retouching, or be revised as being equal to
The Equivalent embodiments of change.Therefore all contents without departing from technical solutions of the utility model, the thinking according to this utility model made
Equivalent equivalence changes, all should be covered by protection domain of the present utility model.
