Abstract
Abstract In a vehicular seating unit having arm rest means between adjacent seats, each intermediate arm rest means is constructed to be lifted slightly for disengagement from a holding member and, additionally, designed to be forwardly pivotable about a pin connection to the lower end of a leg support section such that the arm rest means will then repose in a generally vertical position having a resulting upper extremity that is flush with, or below, the level of the adjacent seating surfaces.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
196 words
In a passenger vehicle seating unit making use of an integrated support frame and having generally horizontal arm rest means and adapted to be positioned between adjacent seats in a multiple seat unit, the improved construction permitting the folding of such arm rest means forwardly and out of the way which comprises, having a generally vertical supporting section extend downwardly from a rearward portion of the arm rest means to a single pivotal connection with a pin means connecting to the seat support framing below the seat level, providing a vertically slotted opening in said supporting section at the pivot pin connection to permit a slight raising and lowering thereof, further providing a separate notch and pin engagement between the lower portion of said supporting section and said seat support framing, whereby there is an engagement therebetween except when said supporting section together with said arm means is lifted out of the engagement and there is a forward pivoting of the combination tHrough about 90* to hang in front of such seat support framing in such position that the back portion of said arm rest means is located substantially level with the top of adjacent seats.

Claim 3
Dependent Claim
68 words
The seating unit of claim 1 further characterized in that the arm rest means has a generally horizontal upper arm rest section extending forwardly from said supporting section and there is an unobstructed forward portion from the latter whereby there can be the rotation of said upper arm rest section over and around any front seat support framing which may extend between adjacent sections of the seating unit.
Claim 4
Dependent Claim
47 words
The seating unit of claim 1 further characterized in that a notch means is provided on said supporting section in the form of an open-ended slot and a pin-like member extends from a side portion of said seat support framing to be engageable with said notch means.
Claim 5
Dependent Claim
84 words
The seating unit of claim 1 further characterized in that channel means extend through the interior of said arm rest means, including said vertical supporting section, to thereby accommodate cable and wiring from passenger control means mounted on said arm rest means, and said channel means exit from the lower portion of said support section close to said pivot pin means such that there is only a small movement of cable and wiring means when the arm rest means is rotated in either direction.
Claim 6
Dependent Claim
47 words
The seating unit of claim 1 further characterized in that the seating unit has multiple placements and at least the intermediate arm rest means between adjacent seats of the unit are movable to lift up and pivot forwardly to hang in front of the seat support framing.
