Abstract
Abstract An arm rest (1) for motor vehicle seats comprising a body (2) and a load bearing structure (4) provided with swinging mounting means relative to a connecting element (9) adapted to be fixed to a lateral side (F) of seat backrest (B). The load bearing structure (4) has a tubular end portion (5) coaxially rotatable on a stationary shaft (7) with rotational friction and with respective stop numbers (24, 13) between a raised position and a lowered position of the arm rest (1).

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
258 words
An arm rest for motor vehicle seats having a backrest with lateral sides, comprising an elongated body and a load bearing structure incorporated in the body and including swinging mounting means of the arm rest comprising a connecting element adapted to be fixed relative to a lateral side of the backrest, a tubular end portion of the load bearing structure oriented transverse to the body, and a shaft coaxially inserted within said tubular end portion and having one end projecting from the body and secured to said connecting element in order to allow rotation on said shaft of said tubular end portion between a raised position and a lowered position of the arm rest, and stop means for stopping rotation of the arm rest in said raised and lowered positions, wherein said tubular end portion has an elastically deformable conformation in a radial direction and is formed interiorly with a pair of opposed axial ribs and with a pair of longitudinal recesses placed on opposite sides of and adjacent to each of said ribs, and wherein the seat is provided externally with a pair of opposed rigid axial projections cooperating with said axial ribs so as to constitute said stop means; said axial projections of the shaft having an outer radial dimension which is substantially equal to the inner radial dimension of said longitudinal recesses of the tubular end portion of the load bearing structure and which is substantially greater than the inner radial dimension of said tubular end portion between the longitudinal recesses adjacent to each other.
Claim 2
Dependent Claim
258 words
An arm rest for motor vehicle seats having a backrest with lateral sides, comprising an elongated body and a load bearing structure incorporated in the body and including swinging mounting means of the arm rest comprising a connecting element adapted to be fixed relative to a lateral side of the backrest, a tubular end portion of the load bearing structure oriented transverse to the body, and a shaft coaxially inserted within said tubular end portion and having one end projecting from the body and secured to said connecting element in order to allow rotation on said shaft of said tubular end portion between a raised position and a lowered position of the arm rest, and stop means for stopping rotation of the arm rest in said raised and lowered positions, wherein said tubular end portion has an elastically deformable conformation in a radial direction and is formed interiorly with a pair of opposed axial ribs and with a pair of longitudinal recesses placed on opposite sides of and adjacent to each of said ribs, and wherein the seat is provided externally with a pair of opposed rigid axial projections cooperating with said axial ribs so as to constitute said stop means; said axial projections of the shaft having an outer radial dimension which is substantially equal to the inner radial dimension of said longitudinal recesses of the tubular end portion of the load bearing structure and which is substantially greater than the inner radial dimension of said tubular end portion between the longitudinal recesses adjacent to each other.
Claim 3
Dependent Claim
74 words
An arm rest according to claim 1, wherein the shaft is formed by an inner metal core having a polygonal cross section and by an outer tubular body of plastic material overmoulded on said core and formed with said opposed axial projections, said core having a terminal portion projecting from the outer tubular body adjacent said one end of the shaft and engage within an opening having a complementary shape of said connecting element.
Claim 4
Dependent Claim
61 words
An arm rest according to claim 1, further comprising axial lock means of the shaft relative to said tubular end portion of the load bearing structure, including an open-ring spring located adjacent to a slit of said tubular end portion and engaging a corresponding groove formed on said outer tubular body of the shaft in proximity of said one end thereof.
Claim 5
Dependent Claim
45 words
An arm rest according to claim 3, wherein said outer tubular body of the shaft is formed adjacent said one end thereof with an annular collar provided with axial bores through which axial fixing screws of the shaft relative to said connecting element are fitted.
Claim 6
Dependent Claim
37 words
An arm rest according to claim 4, wherein said axial bores are elongated slots and the arm rest is provided with manual adjustment means for varying the angular position of said shaft relative to said fixing screws.
Claim 7
Dependent Claim
83 words
An arm rest according to claim 5, wherein said adjustment means comprise a peripheral notch formed in said annular collar of the outer tubular body of the shaft, a cam member substantially radially engaging said peripheral notch, a box-like body interposed between the body of the arm rest and the connecting element, a tubular slide carrying said cam member and slidably guided in said box-like body, and a driving shaft rotatably supported by said box-like body for controlling displacement of said tubular slide.
Claim 8
Dependent Claim
42 words
An arm rest according to claim 1, further comprising disengageable angular locking means carried by said tubular end portion for locking said tubular end portion of the load bearing structure relative to the shaft in said raised position of the arm rest.
Claim 9
Dependent Claim
100 words
An arm rest according to claim 7, wherein said disengageable locking means comprise a push button associated with said one end of the shaft and radially displaceable relative thereto between a retracted locking position and an advance unlocking position, said push button incorporating a hook tooth which, in the raised position of the arm rest, is engaged within a radial seat formed in said tubular end portion of the load bearing structure, elastic means being interposed between said one end of the shaft and said push button and acting so as to urge the latter towards said locking retracted position.
