A fixed guide member that connects the lower end of the belt, guides the shaft in a vertically movable manner, and allows a locking member to be latched in the event of a collision is provided upright from a fixed part such as the vehicle floor or a lower frame of the suspension device; A vehicle seat comprising a shaft rotation prevention member that prevents the lock member from being latched to the fixed guide member unless a large tensile force is applied due to a collision. (2) In the vehicle seat described in claim 1 of the utility model registration claim, the seat belt is constructed by connecting its lower end to the tip of a crank lever provided separately from the locking member on the shaft. Sheet for use. (3) Utility Model Registration In the vehicle seat described in claim 1, the fixed guide member has a vertically elongated hole that guides the shaft in a vertically movable manner, and the lock member rotates rapidly together with the shaft to A vehicle seat characterized by having a configuration in which the front and rear surfaces of the vehicle seat are bitten and latched in a vertically elongated hole. (4) Utility Model Registration In the vehicle seat described in claim 1, the fixed guide member has a vertically elongated guide rail shape, and the lock member has a shape that surrounds the outer periphery of the rail-shaped fixed guide member with a gap. A vehicle seat characterized in that the vehicle seat is configured to be hooked to the fixed guide member from the front and rear by rotating rapidly together with the shaft. (5) Vertical impact/impact on the bottom of the seat cushion
In a vehicle seat equipped with a suspension device that absorbs and alleviates vibrations, a shaft is provided at the rear of the upper frame of the suspension device, and a fixed guide member that guides the shaft so as to be movable up and down is attached to the floor of the vehicle body or the suspension device. a substantially U-shaped holder that stands upright from a fixed part such as a lower frame of the shaft and is attached to the shaft and surrounds the outer periphery of the fixed guide member except for the front side; A locking member consisting of a pivotally supported rotary cam is provided, and the lower end of the seat belt is connected to the end of the locking member on the side opposite to the fixed guide member of the rotary cam. When the rotating cam rotates, the holder is pulled forward and immediately latched onto the fixed guide member from the front and back to prevent the suspension device from tipping forward or being destroyed. 1. A vehicle seat comprising a cam rotation preventing member that prevents a rotating cam and a holder from being latched to a fixed guide member unless a large tensile force is applied.
