Abstract

ABSTRACT OF THE DISCLOSURE

An arm rest for driver's seats, e.g. in forestry machines, comprising an arm rest bar which carries an arm rest pad and at its rear end is pivotally connected to a pivotable link which by pivotal motion permits rising and lowering of the rear end of the arm rest bar, whereas the arm rest bar at the front end thereof is supported by a support rod. The upper end of the support rod is pivotally connected to the arm rest bar by means of a connecting member whereas the lowermost end is movably guided through a turnable and lockable lock or control member.

Description

The present invention generally relates t~ an arm rest, particularly for driver's seats, e.g., in forestry machines.
U.S. Patent Specifications Nos. 1,420,924 and 3,140,119 as well as French Patent Specifica-tion No. l,225,390 illustrate various known adjustable arm rests. However, despite the existence of these and other adjustable arm rests, it has been observed that the sick-leave among machine drivers because of arm-, shoulder- and neck diseases is greatly increasing.
Doctors and physiotherapists claim that one of the reasons for such diseases is a too static working position, inter alia due to the lack of arm rests that are easily adjustable, and above all adjustable to a sufficient extent.
The present invention provides an arm rest for a driver's seat such as is used in forestry machines which remedies the above mentioned drawbacks and which difEers from the previously known arm rests in that; it may be raised and lowered both at the front end and at the rear end; it may be inclined at both the front end and at the rear end; it is adapted for mounting a combination controller which is adjustable into any desired longitudinal, lateral and inclined position; it affords the possibility of a fast adjustment into the desired working position within 15 to 30 seconds~ in comparison with normally about 2 to 4 min.; and in that the arm rest pad is adjustable into a position closer to or further away from the back of the chair.
According to the present invention the arm rest comprises an arm rest bar; an arm rest pad carried by said bar;
a normally horizontal link adapted at one end to be pivotably supported on the machine for relative movement about a first horizontal axis, and pivotably secured at its other end to said bar at the rear portion of said bar for relative movement about ~i ~
~ a second horizontal axis spaced therefrom, whereby pivotable ~ B~
motion about said spaced horizontal axes enables raising and lowering the rear end of said arm rest bar; a bracket secured .
to the front end of said arm rest bar, and adapted to support a universally movable controller of the machine; a normally verticaly support bar having at its upper end a pivotable con-nection with said bracket for enabling relative movement about a third horizontal axis; and a control member adapted to be sup-ported on the machine and guiding the lowerend of said support rod for vertical movement between locked positions, and enabling pivoting o~ the lower end of said support rod about a fourth horizontal axis.
In one embodiment of the present invention the arm rest bar comprises a pair of telescopic tubes adapted to be mutually locked at a selected position for adjustment of the length of said arm rest bar in a direction toward and away from the back of the seat.
In another embodiment of the present invention the arm rest includes a connecting member having a pivotable connection with said bracket for relative movement about a fifth horizontal axis and carrying a universally movable holding bracket for the controller.
The present invention will be further illustrated by way of the accompanying drawing in which the single Figure is a side elevation of an arm rest in àccordance with one embodiment of the present invention.
Referring to the Figure, the arm rest according to the invention is secured to one side of a driver's seat 10, of for example a forestry machine, while a similar arm rest is mounted on the other side ofthe seat 10. As usual, the seat 10 has a seat pad 11 and a back support 12 which is adjustable into desired inclined positions around an axis 12.
On the back support 13, or on a special support panel, there is affixed a bracket 1~ which carries a pivot 15 to pivotally journal one end of a link 16 for relative movement about a first horizontal axis. The other end of the link 16 carries a pivot 17 to pivotally journal one end of a second link or bracket 18 which is rigidly connected to an arm rest bar 19 for relative movement about a second horizontal axis.
The arm rest bar 19 is telescopic and comprises a rear outer tube l9A and a front inner tuhe l9B which are mutually lockable by means of a lock screw 20 having a knob. The outer tube l9A slidably car~ies an arm rest pad 21 which is lockable in any desired adjustment position by means of a screw 22 having a knob.
At its front end the inner tube l9B is provided with a bracket or connecting member 23 to hold a pivot 24 which pivotally carries for relative movement about a horizontal axis herein-after referred to as a fifth horizontal axis,~ a preferably univer-sally movable holding bracket 25 for a combination controller 26 which is shown only diagrammatically. Further, the bracket 23 also serves to pivotally journal one end of a support rod 27 ~for movement about a third horizontal axis,~if desired in the shape of a toothed rack, which passes movably through a turnable and lockable locking or controlling member 28 at the foremost end of the seat pad ll(and enabling the relative pivoting of the lower end of the support rod 24 about a fourth horizontal axis.~
Preferably, the pivots 13, 15, 17 and 24 are of the known self-arresting type, each having an adjustment knob.
In a simplified embodiment it is believed possible to omit the pivot 17 and to combine the links 16, 18 into one simple link, which at the front end thereof is pivotally con-nected to the arm rest bar 19 by means of a single journal pin.
