AI Technical Summary

Technical Problem

Existing seat rotation devices experience unnecessary high force requirements for rotation due to active rattle prevention mechanisms, and there is a desire for compactness in the height direction.

Method used

A seat rotation device with a locking member that switches between locked and unlocked positions, featuring a rattle suppression member that comes into contact with both the support and rotating members in the locked state and creates a gap in the unlocked state, utilizing a ball-bearing mechanism and a rattle suppression member to prevent rattling and facilitate rotation.

Benefits of technology

The device effectively suppresses rattling when stationary and reduces the force required for seat rotation, contributing to compactness and ease of use.

Abstract

To facilitate, in a seat rotating device that allows a seat to be rotated on a base member, rotation of the seat by cancelling a looseness prevention status during the rotation, while preventing looseness during a stationary state of the seat.SOLUTION: A looseness prevention member 20 that is moved in conjunction with a lock member 19 that switches between a locking state for blocking rotation of an annular rotary member 18 supporting a seat frame and an unlocking state is brought into a firm contact with a support member 17 and the annular rotary member 18 in a locking position of the lock member 19. When the rock member 19 is brought to an unlocking position, an empty space occurs between the support member 17 and the annular rotary member 18.SELECTED DRAWING: Figure 5
