Abstract: A horizontal wall is formed with a notch groove. The notch groove is formed by cutting a tip end of the horizontal wall on the side of the vehicle body substantially along an approaching/separating direction between a vehicle body and a slide door. A connecting unit which turnably connects a plate and a roller holder of a connection assembly to each other is movably inserted into the notch groove. The plate and the horizontal wall of the bracket are fastened to each other in a state where they are superposed on each other.

Abstract: A seat back lock is included in a seat back of a vehicle. A knob is provided at the top of the seat back. A passenger in the vehicle pushes down the knob to cause the seat back to move from a standing position to a folding position on a seat. In the standing position, a striker extending from the body of the vehicle engages with a hook of the seat back lock. The seat back lock comprises a binding lever and a warning lever connected to the knob. Whenever the strike engages with the hook, the binding lever directly contacts the striker. If the striker incompletely engages with or disengages from the hook, the knob is pulled down by the warning lever to expose an indicator to permit the passenger to visually recognize it.

Abstract: The output level of vibration of a portion below the spring of a vehicle detected by a sensor, and its frequency is converted to obtain the frequency spectrum of the vibration level. Next, an operation is carried out on at least two vibration levels, at different frequency bands. The computed value is compared with a master curve showing the frequency spectrum of vibration level stored in vibration level storage to estimate the condition of a road surface so as to estimate the running state of the vehicle. Further, the running state of each tire including air pressure is detected from the vibration level of the portion below the spring to estimate the running state of the vehicle. Thereby, a multi-function sensing system is constructed for estimating the condition of a road surface or the running state of the tire with one sensor.
