Abstract
Abstract A seat mounting structure is provided defining a base portion for stationary mounting in a boat hull subject to roll movement and including a rudder control member oscillatable about a first fore and aft extending horizontal axis. A mount portion is supported from the base portion for adjustable vertical shifting relative thereto and a seat structure is oscillatably supported from the mount portion in pendulum fashion for swinging about a second fore and aft extending horizontal axis with the first and second axes disposed at least generally in the same vertical plane and the mount portion being vertically adjustable relative to the first axis to enable at least general horizontal alignment of the first and second axes. In addition, an upwardly opening arcuate footrest is provided for mounting between the seat structure and the rudder control member and the footrest is supported for vertical adjustment whereby the feet of a helmsman seated on the seat structure may be comfortably rested upon the footrest. Also, the base portion of the seat mounting structure and the footrest each include structure whereby they may be independently shifted in fore and aft directions relative to the boat hull.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
143 words
In combination with a sailboat hull subject to roll movement including a rudder control member oscillatable about a first fore and aft extending horizontal axis, a helmsman's seat including mounting structure defining a base portion mounted in said hull and a mount portion supported from said base portion for adjustable vertical shifting relative thereto, a seat structure, support means oscillatably supporting said seat structure from said mount portion in pendulum fashion for swinging about a second fore and aft extending horizontal axis with said first and second axes disposed at least generally in the same vertical plane and said mount portion being vertically adjustable relative to said first axis to enable at least general alignment of said axes, said support means including adjustable friction brake means operative to adjustably vary frictional resistance to oscillation of said seat structure relative to said mount portion.
Claim 2
Dependent Claim
143 words
In combination with a sailboat hull subject to roll movement including a rudder control member oscillatable about a first fore and aft extending horizontal axis, a helmsman's seat including mounting structure defining a base portion mounted in said hull and a mount portion supported from said base portion for adjustable vertical shifting relative thereto, a seat structure, support means oscillatably supporting said seat structure from said mount portion in pendulum fashion for swinging about a second fore and aft extending horizontal axis with said first and second axes disposed at least generally in the same vertical plane and said mount portion being vertically adjustable relative to said first axis to enable at least general alignment of said axes, said support means including adjustable friction brake means operative to adjustably vary frictional resistance to oscillation of said seat structure relative to said mount portion.
Claim 3
Dependent Claim
78 words
The combination of claim 1 including an upwardly opening arcuate footrest, mounting means stationarily mounting said footrest in said hull between said seat structure and said rudder control member at an elevation lower than said seat structure and with said footrest extending transversely of said hull and positioned for engagement by the feet of a helmsman seated in said seat structure, said mounting means including means operative to adjust the elevation of said footrest relative to said hull.
Claim 4
Dependent Claim
26 words
The combination of claim 1 including a forwardly and upwardly and rearwardly and downwardly swingable horizontal transverse footrest supported from said seat structure below the latter.
Claim 5
Dependent Claim
31 words
The combination of claim 1 wherein said base portion and hull include coacting means supporting said base portion from said hull for adjusted fore and aft shifting relative to said hull.
Claim 6
Dependent Claim
112 words
In combination with a sailboat hull subject to roll movement including a rudder control member oscillatable about a first fore and aft extending horizontal axis, a helmsman's seat including mounting structure defining a base portion mounted in said hull and a mount portion supported from said base portion, a seat support means oscillatably supporting said seat structure from said mount portion in pendulum fashion for swinging about a second fore and aft extending horizontal axis with said first and second axes disposed in at least general alignment, said support means including adjustable friction brake means operative to adjustably vary frictional resistance to oscillation of said seat structure relative to said mount portion.
Claim 7
Dependent Claim
112 words
In combination with a sailboat hull subject to roll movement including a rudder control member oscillatable about a first fore and aft extending horizontal axis, a helmsman's seat including mounting structure defining a base portion mounted in said hull and a mount portion supported from said base portion, a seat support means oscillatably supporting said seat structure from said mount portion in pendulum fashion for swinging about a second fore and aft extending horizontal axis with said first and second axes disposed in at least general alignment, said support means including adjustable friction brake means operative to adjustably vary frictional resistance to oscillation of said seat structure relative to said mount portion.
