Smooth sliding is assured.

Welding heat is the primary cause of slider hardening. The mounting frame and sliders of this model are secured with rivets to prevent thermal distortion of the metal sliders. Direct welding of sliders is performed only as an auxiliary process to minimize the number of spot welds. For vehicles that require transfer of the original-equipment seat belt buckle to the seat rail, the seat belt buckle stay is fixed with rivets. Smoother slide is achieved by the elimination of distortion due to welding heat.

The general-purpose side stays accommodate many seat models.

The bolt holes used for mounting the seat itself are cut into elongated and diagonal shapes. In addition, the bolt holes for attaching to the sliders are elongated, which allows for mounting of many seat models. Moreover, in addition to offering fine adjustment of seat height and seat angle, this seat rail provides lateral seat adjustment to the left and right. It is also compatible with seats with a high bolt-hole mounting position,* such as the Recaro RS-G. In addition, weight-relief holes are provided for maximum weight reduction.
* For seats with higher mounting positions at the rear, only the bolt holes at the top of the side stays can be used.

サイドエアバッグキャンセラー付属

Includes side airbag canceller.

Regardless of whether standard or optional equipment is installed, side airbag cancellers are provided to prevent the triggering of warning lights in models equipped with side airbags.

Super-low-profile model​

Super-low-profile model

For vehicles requiring a low seating position, such as sports cars, we offer a Super-low-profile model that is a lower-profile version of the Standard model. As the driver’s hip point approaches the center of gravity of the vehicle, the driver experiences more accurate feedback from the car, such as vehicle handling and road conditions.

Tips for mounting the seat to the side stays

Mount the seat to the side stays as orientated in the illustrations below. The installation width of the seat to be installed determines the orientation.
Adjustments required to center the seat relative to the steering wheel (adjusting the seat to the left or right) are performed by changing the orientation of the side stays as they mount to the seat rails.
Use spacers if the grommets of the belt holes interfere with the side stays, creating a gap between the seat body and the side stays.
(Adjust the number of spacers to fill the gap.)
Even if no interference occurs, a gap may be present depending on the width of the seat to be mounted. In that case, use spacers as well. (Use 30-mm bolts when using spacers; use 20-mm bolts when not using spacers.)

Note: Various spacers and bolts are included with the seat rail.

“Seat mounting width” explained


We suggest measuring the width of the seat across its bottom as shown in the image. Measure from the surfaces that mount to the side stays.

If the front and rear of the seat vary in width, measure the seat at its widest point.
