摘要:
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.

The vibration of a tire 10 of a running vehicle in the circumferential direction or the width direction is detected by a road surface condition estimating tire 10, provided with an acceleration sensor 11 and a signal processing unit 12. Data of a detected vibration waveform are divided into data of three domains, namely, a pre-leading domain, a contact patch domain, and a post-trailing domain, and then the vibration levels in the pre-leading domain and the contact patch domain, respectively, are extracted. At the same time, a vibration component in a low-frequency band and a vibration component in a high-frequency band are extracted respectively from the vibration levels in the respective domains, and respective vibration level ratios R, which are each a ratio thereof, are calculated. Then, on the vehicle body side, the condition of a road surface on which the vehicle is running is estimated, based on the calculated vibration level ratio R and a map 32M, stored in a storage means 32, showing a relationship between the vibration level ratio R of tire vibration and road surface conditions. Thus a road surface condition can be estimated with accuracy even when there are changes in temperature or vehicle speed.

摘要:
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.

摘要:
A method capable of estimating a snowy road surface condition during vehicular travel in finer classification. In this method, tire vibrations in the circumferential direction, road surface temperature (T), and tire-generated sound are detected by an acceleration sensor, a road surface thermometer, and a microphone, respectively. Then band values P11, P12 and P13 for a pre-leading-edge region (R1), band values P21, P22 and P23 for a leading-edge region (R2), band values P31, P32 and P33 for a pre-trailing-edge region (R3), band values P41 and P42 for a trailing-edge region (R4), and band values P51, P52 and P53 for a post-trailing-edge region (R5) are calculated from the tire vibration data. A sound pressure level ratio (Q)=(PA/PB), which is the ratio of a band power value (PA) of a low frequency band to a band power value (PB) of a high frequency band, is calculated from data on the tire-generated sound. And a road surface condition is estimated, using the band values (Pij), road surface temperature data (T), sound pressure level ratio (Q), and wheel speed data.
摘要:
A purpose of the present invention is to provide a rim wheel and a tire rim assembly which are capable of effectively reducing cavity resonance of a tire, and accordingly, enhancing quietness and riding comfort. A plurality of cap members 20 is arranged on an outer circumferential surface of a rim 16 in a circumferential direction thereof, diaphragms are disposed inwardly of each cap member 20, and a plurality of sub-air chambers 32 is formed between the rim 16 and the cap members 20 in a rim circumferential direction. The tire main air chamber 18 is connected to the sub-air chambers 32 through communicating holes 24 formed on the cap members 20. The sub-air chambers 32 and the communicating holes 24 constitute a Helmholtz resonance noise absorber that can absorb vibration with specified frequencies. Further, since the sub-air chamber 32 is not formed in a continuous annular shape in a tire circumferential direction, occurrence of cavity resonance can be suppressed and a substantial reduction in noise can be secured.
