RAIL VEHICLE EQUIPPED WITH LONG SEAT HAVING ARMREST THAT INCORPORATES IMPACT RELAXATION STRUCTURE

PROBLEM TO BE SOLVED: To provide a rail vehicle equipped with a long seat having a collision relaxation structure capable of suppressing a passenger's being thrown out of the long seat, and relaxing an impact applied to a passenger even when the rail vehicle equipped with a long seat (seat) to which an armrest is attached collides and slows down significantly in a short time.SOLUTION: In a rail vehicle equipped with a long seat including a backrest support part provided along a longitudinal direction of the rail vehicle for supporting a backrest, a seating surface support part provided along the backrest support part for supporting a seating surface, and an armrest that partitions the seating surface, the armrest includes a first slide part to which one end part of the armrest is connected and which slides along the backrest support part, and a connection part which rotatably connects the other end part of the armrest to the seating surface support part. An angle formed by the armrest and the backrest support part when a passenger collides with the armrest is an acute angle.SELECTED DRAWING: Figure 5 【課題】 肘掛が取付けられたロングシート（座席）を備える軌条車両が衝突して短時間に大きく減速する場合であっても、乗客がロングシートから投げ出されることを抑制するとともに乗客に加わる衝撃を緩和できる衝突緩和構造を備えるロングシートを有す軌条車両を提供することである。【解決手段】 軌条車両の長手方向に沿って備えられるとともに背もたれを支持する背もたれ支持部と、背もたれ支持部に沿って備えられるとともに座面を支持する座面支持部と、座面を区画する肘掛を有すロングシートを備える軌条車両において、肘掛は肘掛の一方の端部が接続するとともに背もたれ支持部に沿ってスライドする第１スライド部と、肘掛の他方の端部を座面支持部に回動可能に接続する接続部を備え、乗客が肘掛に衝突した時に肘掛と背もたれ支持部とがなす角度が鋭角となることを特徴とする軌条車両によって解決できる。【選択図】 図５
