Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
238 words
A birthing chair comprising: (a) an essentially horizontal seat portion having a width from a first side edge to a second side edge, and a depth from a front edge to a back edge, said horizontal seat portion having an essentially U-shaped opening extending from said front edge; (b) a backrest attached to said seat portion proximate said back edge; (c) a plurality of legs supporting said seat portion, including at least one leg on said first side edge and a second leg on said second side edge; (d) a handgrip attached to each of said opposing side edges of said seat portion; (e) an essentially planar work surface extending at least partially between said first and second legs, said planar work surface having a first end and an opposing second end, said planar work surface means proximate a first end thereof to connect said planar work surface to said first and second legs, said planar work surface being positioned below said horizontal seat portion and being suitable to rest thereon a newly born baby; (f) a footrest mountable on said second end of said planar work surface, said footrest being mounted substantially perpendicular to said planar work surface; and, (g) means for connecting said first end of said planar work surface to said first and second legs in a manner whereby the distance of said footrest from said front edge of said seat portion is selectively changeable.
Claim 2
Dependent Claim
238 words
A birthing chair comprising: (a) an essentially horizontal seat portion having a width from a first side edge to a second side edge, and a depth from a front edge to a back edge, said horizontal seat portion having an essentially U-shaped opening extending from said front edge; (b) a backrest attached to said seat portion proximate said back edge; (c) a plurality of legs supporting said seat portion, including at least one leg on said first side edge and a second leg on said second side edge; (d) a handgrip attached to each of said opposing side edges of said seat portion; (e) an essentially planar work surface extending at least partially between said first and second legs, said planar work surface having a first end and an opposing second end, said planar work surface means proximate a first end thereof to connect said planar work surface to said first and second legs, said planar work surface being positioned below said horizontal seat portion and being suitable to rest thereon a newly born baby; (f) a footrest mountable on said second end of said planar work surface, said footrest being mounted substantially perpendicular to said planar work surface; and, (g) means for connecting said first end of said planar work surface to said first and second legs in a manner whereby the distance of said footrest from said front edge of said seat portion is selectively changeable.
Claim 3
Dependent Claim
53 words
A birthing chair as recited in claim 1, wherein said backrest is attached to said seat portion at an angle that maximizes the pushing effort upon said backrest by a woman delivering a baby during certain phases of the delivery and is also comfortable to rest against during other phases of the delivery.

Dependent Claim
68 words
A birthing chair as recited in claim 1, wherein said selective connecting means comprises a rod that is connectable to an engaging means on said planar work surface, one end of said rod being secured to said first leg and the remaining end of said rod being secured to said second leg, said rod being secured to said legs at a point intermediate the length of said legs.
Claim 5
Dependent Claim
41 words
A birthing chair as recited in claim 3, wherein said engaging means for connecting said planar work surface to said first and second legs comprises a slotted member, said slotted member having a plurality of notches for engaging to said rod.
Claim 6
Dependent Claim

A birthing chair as recited in claim 1, wherein said footrest is selectively and slidably mountable on said second end of said planar work surface.
Claim 12
Dependent Claim
50 words
A birthing chair as recited in claim 1, wherein said first end of said planar work surface is positionable at a distance further from said front edge of said horizontal seat portion than the distance at which said U-shaped opening extends from said front edge of said horizontal seat portion.
Claim 13
Dependent Claim
25 words
A birthing chair as recited in claim 1, wherein said planar work surface is essentially continuous from said first end to said second end thereof.
Claim 14
Dependent Claim
