Abstract
(EN) Provided is a vehicle seat such that the characteristics of an S-spring can be changed by a simple configuration and therefore improved seating performance can be achieved by changing the characteristics of the S-spring according to the body type of an occupant. In a vehicle seat (1) in which an S-spring (6) is extended on a seat cushion frame which supports a seat cushion on which an occupant is to be seated, a restricting member (13) for partially restricting the extending deformation of the S-spring (6) is detachably attached to the S-spring (6). The restricting member (13) is provided with: a pair of wire hook portions (15, 16) hooked onto a lateral line portion (8) and a rear-end lateral line portion (12) of the S-spring (6); and an elongated wire portion (14) connecting the pair of wire hook portions (15, 16). By hooking the pair of wire hook portions (15, 16) of the restricting member (13), the extensional rigidity of the S-spring (6) can be increased, and by changing the hooked position of the pair of wire hook portions (15, 16) of the restricting member (13), the deflection rigidity of the S-spring (6) can be changed.
(FR) L'invention concerne un siège de véhicule tel que les caractéristiques d'un ressort en S peuvent être changées par une simple configuration et par conséquent une amélioration de la performance d'assise est possible en changeant les caractéristiques du ressort en S en fonction des caractéristiques corporelles d'un occupant. Dans un siège de véhicule (1) dans lequel un ressort en S (6) est étendu sur un cadre de coussin de siège qui supporte un coussin de siège sur lequel un occupant doit s'asseoir, un élément de restriction (13) permettant de limiter partiellement la déformation d'extension du ressort en S (6) est attaché de manière détachable au ressort en S (6). L'élément de restriction (13) comporte : une paire de parties de type crochet métallique (15, 16) accrochées sur une partie de type ligne latérale (8) et une partie de ligne latérale d'extrémité arrière (12) du ressort en S (6) ; et une partie de fil allongé (14) raccordant la paire de parties de type crochet métallique (15, 16). En accrochant la paire de parties de type crochet métallique (15, 16) de l'élément de restriction (13), la rigidité d'extension du ressort en S (6) peut être augmentée, et en changeant la position accrochée de la paire de parties de type crochet métallique (15, 16) de l'élément de restriction (13), la rigidité de flexion du ressort en S (6) peut être changée.
(JA)  簡素な構成でSばねの特性を変更することができるため、乗員の体格に応じてSばねの特性を変更することで、着座性能を向上させる車両用シートを提供する。 乗員が着座するシートクッションを支持するシートクッションフレームにSばね6が張設された車両用シート1において、このSばね6に着脱自在に取り付けられてSばね6の伸張変形を部分的に拘束する拘束部材13を設ける。拘束部材13は、Sばね6の横線部8及び後端横線部12に引っ掛ける一対のワイヤフック部15,16と、一対のワイヤフック部15,16を連結する長尺のワイヤ部14とを備える。そして、拘束部材13の一対のワイヤフック部15,16を引っ掛けることで、Sばね6の伸び剛性を高くすることができ、拘束部材13の一対のワイヤフック部15,16を引っ掛ける位置を変更することで、Sばね6の撓み剛性を変更することができる。
