Abstract
An armrest assembly adapted for mounting on the back portion of a motorcycle seat includes armrests that are pivotably mounted for pivoting about horizontal and vertical axes. Pivoting about either axis is possible from the normal position, and pivoting can be effected merely by applying a moment to the armrest about the desired axis. As a result, rapid dismounting during an emergency is readily permitted.
Claims13
An armrest assembly for mounting on a seat having a seat portion and a back portion, comprising:
- a. a support adapted for mounting on the back portion of the seat with its forward face disposed thereagainst;
- b. a pair of armrests disposed on opposite sides of said support to extend along opposite sides of the associated seat, each armrest having one end pivotably supported on said support for pivoting relative to said support about a first axis, said first axis extending substantially parallel to the plane of said forward face to lie generally parallel to the planes of said seat and back portions when said support is mounted on the associated seat, by application of a moment to said armrest about said first axis from a first stable position of said armrest, in which said armrest extends substantially perpendicularly to the plane of the forward face and thereby to the associated back portion along the side of the seat when said support is mounted on the back portion, said pivoting from said first position being through an arc of at least about fifteen degrees to a second stable position thereof, each of said armrests also being pivotable relative to said support about a second axis substantially perpendicular to said first axis by application of a moment to said armrest about said second axis, said pivoting producing movement of said armrest from said first position of said armrest through an arc of at least about fifteen degrees about said second axis to a third position thereof in which ease of dismounting from the seat is permitted when said support is mounted on the back portion of the seat;
- and
- c. bias means associated with each armrest and applying a moment about said second axis to said armrest to bias said armrest in said first position when said armrest is in said first position and to bias said armrest in said third position when said armrest is in said third position, the moment applied by said bias means being lower when said armrest is in a range of positions intermediate between said first and third positions than when said armrest is in said first position.

A seat assembly comprising:
- a. a seat having a seat portion and a back portion;
- b. a support mounted on said back portion with its forward face disposed thereagainst;
- c. a pair of armrests disposed on opposite sides of said support and of said seat, each armrest having one end pivotably supported on said support for pivoting relative to said support about a first axis extending substantially parallel to the planes of said forward face and said seat portion of said seat by application of a moment to said armrest about said first axis, said pivoting producing movement of said armrest between a first stable position, in which said armrest extends substantially perpendicularly to the plane of said forward face and thereby to said back portion along the side of said seat, through an arc of at least about fifteen degrees to a second stable position for ease of mounting said seat from the side thereof, each of said armrests also being pivotable relative to said support about a second axis substantially perpendicular to said first axis by application to said armrest of a moment about said second axis, said pivoting producing movement of said armrest from said first position of said armrest through an arc of at least about fifteen degrees about said second axis to a third stable position, in which said armrest is disposed relatively outwardly of said seat from said first position to permit ease of dismounting from said seat;
- and
- d. bias means associated with each armrest and applying a moment about said second axis to said armrest to bias said armrest in said first position when said armrest is in said first position and to bias said armrest in said third position when said armrest is in said third position, the moment applied by said bias means being lower when said armrest is in a range of positions intermediate between said first and third positions than when said armrest is in said first position.
