Abstract

A boat captain'"'"'s helm chair has a seat part which is movable forwardly and rearwardly relative to a support, and a backrest with a retaining member such that its forward movement is counteracted. The forward portion of the seat part is rounded relative to the remaining portion to provide a support for the user in both a sitting and semi-standing rearward leaning postural position. Side portions of the seat extend forwardly of its mid portion to prevent lateral movements of the user. A compressive distortion of the armrest is counteracted by a dense U-shaped shock absorber to prevent the distortion of the armrest from constant use.

Claims

1. A boat captain'"'"'s helm chair, comprising a stationary upright support adapted for securement to a suitable deck;

an adjustably positioned mounting bracket releasably secured to said upright support to provide for vertical seat adjustment;

a seat frame chassis having parallel rods secured thereto between a front and a back of said seat frame chassis;

the mounting bracket releasably secured to said parallel rods to adjustably secure said seat frame chassis horizontally in relation to said mounting bracket;

a seat cushion secured to said seat frame chassis, a seat frame bracket extending upwardly from said seat frame chassis on each side of said seat cushion;

a back support chassis having opposing back support brackets extending from a lower portion of said back support'"'"'s chassis, with a means to releasably secure said back support chassis to said seat frame bracket at a selected angular position in relation to said seat female member;

a back support cushion secured to said back support chassis, said back support cushion having inwardly tapered opposing side wing portions;

opposing armrests each secured to an arm rest bracket, search said arm rest bracket extending from an arm rest frame for pivotal mounting to said respective back support brackets to selectively, adjustably position said armrests between a first, generally lowered, extended position and a second, generally raised position in relation to said back support chassis;

said opposing armrests each having a dense base shock absorber element with opposing sides of said shock absorber element tapering outward and upward towards the sides of each said armrest, with a less dense upper portion extending between said outward and upward opposing sides of said shock absorber element.

2. The helm chair as defined in claim 1, wherein a footrest is adjustably secured to the stationary upright support at a selected location beneath the seat mounting bracket.

3. The helm chair as defined in claim 1, wherein a means to counteract outward compressive distortion of said armrest is provided, said means comprising said sense base shock absorber element being tapered outward and upward towards said sides of each said armrest with said less dense portion extending between said outward and upward opposing sides of said shock absorber element, such that said less dense upper portion is cradled within and above said outer dense portion.
