AI Technical Summary

Technical Problem

Existing seat slide devices in vehicles increase weight and manufacturing costs due to the inclusion of a separate roller support bracket to suppress vertical rattle, and require additional manufacturing steps.

Method used

A vehicle seat slide device with a rattle suppression member biased by a first biasing member directly attached to the upper rail, utilizing a U-shaped wire spring and locking mechanisms to restrict movement, reducing the need for a separate roller support bracket and simplifying manufacturing.

Benefits of technology

The device effectively suppresses vertical rattle while minimizing weight and manufacturing costs by integrating the biasing member directly onto the upper rail, using a U-shaped wire spring and locking mechanisms to stabilize the rattle suppression member.

Abstract

To provide a vehicle seat sliding device that can suppress vertical rattle while keeping weight and manufacturing costs down. [Solution] The vehicle seat sliding device comprises a lower rail 11 having a bottom wall 11a along the seat mounting surface and an upper wall 11c facing the bottom wall above with a space in between; an upper rail 12 slidably mounted relative to the lower rail; a sliding roller 123 that abuts against the upper surface of the bottom wall 11a of the lower rail 11 and is rotatable; a rattle suppression roller 13 that is relatively movable in the vertical direction relative to the upper rail 12; and a first biasing member 14 that biases the rattle suppression roller 13 to abut against the upper wall 11c. The first biasing member 14 is directly attached to the upper rail 12.
