Abstract: Vehicle seat including: a seat back pivoted to a side of the floor, a seat cushion pivoted to the seat back; and a front leg element having an upper end pivoted to the seat cushion and a lower end pivotally locked to the side of floor in a releasable manner, thus normally providing a four-pivotal-point linkage in the seat. Maintaining the four-pivotal-point linkage adversely restricts design and actions of the seat. Inequality conditions are therefore set in that four-pivotal-point linkage, such that folding down the seat back by an angle exceeding a predetermined angle results in unlocking of the lower end of the front leg element from the side of floor, thereby destroying the four-pivotal-point linkage. Hence, a freedom of design is increased for the seat and floor. Further, leverage mechanism(s) may be provided to facilitate the ease of unlocking the front leg element from the side of floor.

Abstract: In the case of a seat with an armrest on an automobile, an armrest lock mechanism may be released by, for example, the gravitational acceleration(G) in the event of vehicle collision. Accordingly, it is necessary to provide an anti-G spring for biasing to prevent the lock mechanism from being easily released. The purpose of the present invention is to provide an armrest unlocking device that enables a decrease in size of the anti-G spring. In order to solve the problem, provided is an armrest unlocking device in gear, the device operating such that the locking of the lock gear and the sector gear can be released by operating a lever link bracket so as to raise the lock gear, wherein the lock gear has a center of rotation thereof aligned with the position of the center of gravity.

Abstract: The present invention provides a seat which reduces the load applied to a first fastening part, is unlikely to cause wrinkles or slack in a surface cover, and makes surface sheet attachment and detachment simple. To this end, a first fastening part and a second fastening part of a seat are attachable and detachable; hence, it is possible to easily exchange a surface cover according to the season and to clean the surface cover. The second fastening part attachably/detachably connects the surface cover and the rear-surface cover to one another. As a result, the second fastening part appropriately reduces the load directly applied to the first fastening part, making it possible to prevent damage to the first fastening part, and making it unlikely for wrinkles or slack to occur in the surface cover. Furthermore, the second fastening part is the same color and hue at each suspended section; hence, aligning the surface sheet position is easy.
