Abstract
A vehicle-mounted seat device includes an SB main frame, a backrest, an SB subframe, and one or more front-back position regulation mechanisms for regulating the position of the SB subframe in the front-back direction relative to the SB main frame. Each front-back position regulation mechanism includes a front restraining bracket secured relative to the SB main frame, a rear restraining bracket secured on the SB subframe, and a front-back wire strung between the front and rear restraining brackets. The rear restraining bracket is deformed such that its front end portion is displaced rearward relative to its end portion upon input of a load greater than a predetermined load. A maximum pulling load of the front-back wire is greater than a load that causes initial deformation of the rear restraining bracket.
