  • Patent number: 10434911
    Abstract: A vehicle seat includes; a pair of frame members, the frame members forming a frame of at least one of a seat cushion and a seat back and being disposed at positions surrounding a seat region supporting an occupant with an interval therebetween; and a cloth spring member bridged between the frame members to cover the seat region. The cloth spring member has a shorter length in a bridging direction at least on one end side of the frame member in a longitudinal direction of the frame member than in a center portion of the frame member in the longitudinal direction; and the cloth spring member has elasticity.

  • Publication number: 20190203825
    Abstract: An actuator includes a motor including a first rotor rotatable in a circumferential direction, and a stator to drive the first rotor; a second rotor rotatable in the circumferential direction; and a speed reducer that reduces rotation of the first rotor and transmits a torque to the second rotor via a bearing. The first and second rotors include first and second tube portions extending in an axial direction, respectively. The second tube portion is radially outward of the first tube portion. A lubricant is filled in a filling space including at least a portion of a space between an outer surface of the first tube portion and an inner surface of the second tube portion. The actuator includes a width reducing portion that reduces a width of the filling space in a radial direction in at least a portion of the filling space in the axial direction.

  • Patent number: 10280816
    Abstract: A planetary rotor includes: a planetary gear engaged with a driving rotor and a driven rotor on an eccentric side; and a single sequence type planetary bearing having an outer ring held by the planetary gear, an inner ring supported by a planetary carrier in the radial direction and receiving a restoring force from an elastic component, and a plurality of spherical rolling elements interposed between the outer ring and the inner ring. The outer ring is arranged to form a rolling contact part in contact with the spherical rolling element on the eccentric side, with a contact angle to a specific side in the axial direction. A thrust-bearing part where the driving rotor is supported by the driven rotor on the specific side and on the eccentric side is located closer to a rotation center line of the driven rotor than the rolling contact part is.

  • Patent number: 10060305
    Abstract: A control device has two modes as control modes of an electric power supply to an electromagnetic solenoid, which are used when a first determining unit determines that a difference between a sensed value of a phase and a target value of the phase exceeds a permissible range. One of the modes is a special mode that is used when a second determining unit determines that the sensed value of the phase reaches a threshold value. Another one of the modes is a normal mode that is used when the second determining unit determines that the sensed value of the phase does not reach the threshold value. In the special mode, the control device controls supply of the electric power to the electromagnetic solenoid in such a manner that an opening degree of an advancing port is larger than the opening degree of the advancing port in the normal mode.

  • Patent number: 9816407
    Abstract: When a lock demand of a camshaft phase occurs, a control mode of a hydraulic control valve is switched to a locking mode after the camshaft phase is controlled to a lock phase, and a lock pin is moved to a lock position. The camshaft phase is locked at the lock phase, and timing advance and timing retard chambers communicate with each other through a back space. In this state, a locking time filling control is executed. In the locking time filling control, the control mode of a hydraulic control valve is switched to a filling mode, the hydraulic oil is supplied to a timing advance chamber, both of the timing advance chamber and the timing retard chamber are filled with the hydraulic oil, the back space is filled with the hydraulic oil, and thereafter the control mode of the hydraulic control valve is returned to the locking mode.

  • Patent number: 9583248
    Abstract: In a solenoid of a hydraulic pressure control apparatus, a region adjacent to an oil flow guide portion of a stopper breathing passage is formed in a magnetism application region, through which a leakage magnetic flux leaking from a magnetic circuit at a time of turning on of a coil passes. Thereby, magnetic foreign objects made of iron or iron containing material are magnetically attracted to the leakage magnetic flux, so that intrusion of the foreign objects from an outside of the solenoid into a second volume variable chamber through the stopper breathing passage is limited.

  • Publication number: 20160108771
    Abstract: When a lock demand of a camshaft phase occurs, a control mode of a hydraulic control valve s switched to a locking mode after an actual camshaft phase is controlled to a lock phase, and a lock pin (an inner pin and an outer pin) is moved to a lock position. Thus, the camshaft phase is locked at the lock phase, and a timing advance chamber and a timing retard chamber are made a state of communicating with each other through a back space. In this state, a locking time filling control is executed. In the locking time filling control, the control mode of a hydraulic control valve is switched to a filling mode, the hydraulic oil is supplied to a timing advance chamber, both of the timing advance chamber and the timing retard chamber are filled with the hydraulic oil, the back space is filled with the hydraulic oil, and thereafter the control mode of the hydraulic control valve is returned to the locking mode.
