Abstract
Abstract An arm rest is provided which can be lifted by rotation around a transverse shaft so as to completely disappear between two adjacent seats, said arm rest having a rear element articulated on a transverse shaft and a forward interior element which is a prolongation of said rear element and which is articulated on the latter for rotary movement through a pivot the axis of which is longitudinal.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
280 words
A seat structure useful for transportation vehicles and embodying at least two, side-by-side seats with back rests, and an arm rest pivotally mounted on said seat structure between said side-by-side seats for pivotal movement in a vertical plane between a normal, horizontal orientation of said arm rest and a retracted position with said arm rest disposed in a space between said side-by-side seats, said seat structure being characterized by an arm rest having a rear element and a forward element which is a prolongation of said rear element, said rear element having a width such that it will fit in the space between said seats and said forward element having an arm support surface of a width wider than said rear element and wider than said space between said seats and a depth such that said forward element will fit in said space between said seats, means pivotally mounting would rear element on said seat structure to effect said pivotal movement of said elements in unison between said normal, horizontal orientation of said arm rest and said retracted position in the space between said seats, and means for rotating said forward element with respect to said rear element through an angle of 90° about an axis extending longitudinally of said forward element between a first orientation of said arm support part wherein its width is in a horizontal plane and said arm support part can serve comfortably as an arm rest for both seats and a second orientation wherein said arm support surface is in a substantially vertical plane, whereby said forward element will fit in the space between said seats upon pivoting said arm rest to said retracted position.
Claim 2
Dependent Claim
280 words
A seat structure useful for transportation vehicles and embodying at least two, side-by-side seats with back rests, and an arm rest pivotally mounted on said seat structure between said side-by-side seats for pivotal movement in a vertical plane between a normal, horizontal orientation of said arm rest and a retracted position with said arm rest disposed in a space between said side-by-side seats, said seat structure being characterized by an arm rest having a rear element and a forward element which is a prolongation of said rear element, said rear element having a width such that it will fit in the space between said seats and said forward element having an arm support surface of a width wider than said rear element and wider than said space between said seats and a depth such that said forward element will fit in said space between said seats, means pivotally mounting would rear element on said seat structure to effect said pivotal movement of said elements in unison between said normal, horizontal orientation of said arm rest and said retracted position in the space between said seats, and means for rotating said forward element with respect to said rear element through an angle of 90° about an axis extending longitudinally of said forward element between a first orientation of said arm support part wherein its width is in a horizontal plane and said arm support part can serve comfortably as an arm rest for both seats and a second orientation wherein said arm support surface is in a substantially vertical plane, whereby said forward element will fit in the space between said seats upon pivoting said arm rest to said retracted position.
Claim 3
Dependent Claim
41 words
A seat structure as claimed in claim 1, wherein the rear element is mounted on means providing a horizontal axis of rotation which is transverse to said vertical plane and the forward element is mounted for rotation on a longitudinal shaft.
Claim 4
Dependent Claim
68 words
A seat structure as claimed in claim 1 wherein said forward element includes a cam, one face of which at least when the arm rest is in normal position prior to its rotation with respect to said rear element presses against a lug member fixed to the seat structure, the contacting surfaces of said cam and said lug member being in a plane other than a vertical plane.
Claim 5
Dependent Claim
46 words
A seat structure as claimed in claim 3 wherein the contacting surfaces of said cam and said lug member are contained in a plane parallel with a transverse pivot shaft of said rear element and slanted relative to the vertical by an angle of approximately 20°.
Claim 6
Dependent Claim
41 words
A seat structure as claimed in claim 3 wherein the plane of the contacting surfaces of said cam and said lug member is a slanted plane, from top to bottom and from the rear to the front of the arm rest.
Claim 7
Dependent Claim
43 words
A seat structure as claimed in claim 3 wherein a small bridge on said rear element constitutes a stop member for said cam when the forward element of the arm rest pivots around its longitudinal axis by 90° relative to said rear element.
Claim 8
Dependent Claim
46 words
A seat structure as claimed in claim 1 wherein said means for rotating said forward element with respect to said rear element embodies pivot means providing pivotal movement of said forward element relative to said rearward element uniquely about a longitudinal axis through the arm rest.
Claim 9
Dependent Claim
38 words
A seat structure as claimed in claim 1 wherein the rear part of said forward element has a cylindrical pivot which cooperates with the cylindrical rim of a ring affixed to the forward part of said rear element.
Claim 10
Dependent Claim
39 words
A seat structure as claimed in claim 8 wherein a cam is mounted on said pivot in the rear of said ring, a washer being placed between the ring and the cam, movable in rotation relative to said ring.
Claim 11
Dependent Claim
41 words
A seat structure as claimed in claim 9 wherein said pivot is mounted on a mounting riveted to the rear part of said forward element and said ring is mounted on a mounting articulated on a transverse shaft between said seats.
Claim 12
Dependent Claim
35 words
A seat structure as claimed in claim 1 wherein said space between said seats is a space between the back rests of said seats in which said arm rest is accommodated in said retracted position.
Claim 13
Dependent Claim
35 words
A seat structure as claimed in claim 11 wherein said rear element is mounted on means providing a horizontal axis of rotation which is transverse to said vertical plane and located between said back rests.
