Abstract

Abstract Foldable arm rest assembly for vehicle seats in which first and second pairs of connection means connect to an armrest and seat structure to upper and lower ends of crossed arms, one pair of connection means being pivotal connections and the other including one pivotal and one slidable connection. Locking means are associated with the slidable connection and with the crossing portions of the arms, the locking means being held engaged by gravity and by downward pressure on the arm rest and being releasable by upward movement of the arm rest.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 214 words
In an assembly for supporting an arm rest from a lower fixed support for vertical movement between a lowered inoperative position adjacent the fixed support and an elevated operative position spaced upwardly a substantial distance from the fixed support, first and second arms for extending in crossing relationship between the armrest and the lower fixed support, first and second pivot means pivotally connecting the lower ends of said first and second arms to the fixed support for pivotal movement about first and second fixed horizontal axes in parallel relation, one of said first and second axes being spaced rearwardly from the other, third pivot means pivotally connecting the upper end of said first arm to the arm rest on a third axis in fixed relation to the arm rest and parallel to said first and second axes, fourth pivot means connecting the upper end of said second arm to the arm rest for movement about a fourth axis parallel to said first and second axes and movable forwardly and rearwardly relative to the arm rest during vertical movement of the arm rest between side lowered and elevated positions thereof, and locking means for releasably fixing the position of said fourth axis relative to the arm rest in said elevated position of the arm rest.
Claim 2
Dependent Claim 214 words
In an assembly for supporting an arm rest from a lower fixed support for vertical movement between a lowered inoperative position adjacent the fixed support and an elevated operative position spaced upwardly a substantial distance from the fixed support, first and second arms for extending in crossing relationship between the armrest and the lower fixed support, first and second pivot means pivotally connecting the lower ends of said first and second arms to the fixed support for pivotal movement about first and second fixed horizontal axes in parallel relation, one of said first and second axes being spaced rearwardly from the other, third pivot means pivotally connecting the upper end of said first arm to the arm rest on a third axis in fixed relation to the arm rest and parallel to said first and second axes, fourth pivot means connecting the upper end of said second arm to the arm rest for movement about a fourth axis parallel to said first and second axes and movable forwardly and rearwardly relative to the arm rest during vertical movement of the arm rest between side lowered and elevated positions thereof, and locking means for releasably fixing the position of said fourth axis relative to the arm rest in said elevated position of the arm rest.
Claim 3
Dependent Claim 18 words
In an assembly as defined in claim 1, said first axis being spaced forwardly from said second axis.
Claim 4
Dependent Claim 43 words
In an assembly as defined in claim 1, said fourth pivot means comprising a pin carried by the upper end of said second arm, and an elongated member secured to the arm rest and having an elongated horizontally extending slot receiving said pin.
Claim 5
Dependent Claim 35 words
In an assembly as defined in claim 3, said locking means comprising an upwardly extending portion at one end of said slot receiving said pin when the arm rest is in said elevated position thereof.
Claim 6

In an assembly as defined in claim 1, one of said arms having an elongated slot therein, and a pin carried by the other of said arms and slidable in said slot.
Claim 7
Dependent Claim 36 words
In an assembly as defined in claim 5, said slot having a transversely extending portion at the upper end thereof for releasable lockable engagement with said pin when the armrest is in said elevated position thereof.
Claim 8
Dependent Claim 90 words
In an assembly as defined in claim 1, said first axis being spaced forwardly from said second axis, said first arm comprising a member of metal tubing having first and second portions at right angles to provide a generallY L-shaped configuration, said first pivot means including means fitted into the end of said first portion, said third pivot means comprising an elongated member supporting the arm rest and a pin connecting the rearward end of said elongated member and the upper end of said second portion of said metal tubing.
Claim 9
Dependent Claim 38 words
In an assembly as defined in claim 7, said elongated member having a longitudinally extending slot therein, said fourth pivot means comprising a pin carried by the upper end of said second arm and extending into said slot.
Claim 10
Dependent Claim 47 words
In an assembly as defined in claim 8, said second arm being of flat metal stock and having a longitudinal slot therein, and a second pin carried by said second portion of said member of metal tubing and extending into said longitudinal slot and said second arm.
