Abstract: A vehicle body front section structure is provided with longitudinal frame members that are connected by curved parts to the back surface of a widthwise frame member to disperse the load when the vehicle undergoes a front collision. In particular, wedge-shaped open spaces exist between the back surface of the widthwise frame member and the wall surface of the curved part of each longitudinal frame member that faces the back surface. Consequently, when the vehicle undergoes a front collision, the rearward collapsing of the widthwise frame member causes the curved part to gradually undergo bending deformation while being folded over in such a manner that the wall surface thereof that faces the back surface touches against the back surface.

Abstract: A headrest apparatus for a vehicle has a headrest body 10a provided with a left headrest member 11 and a right headrest member 12 and a locking unit 40 for holding the left and right headrest members 11, 12 at their initial positions. At a vehicle rear-end collision, the locking unit 40 is released by a control unit 50 for detecting the vehicle rear-end collision. As a result, the left and right headrest members 11, 12 rotate forward about the vehicle, so that a sheet 13 stretched between respective separation ends of the members 11, 12 is unfolded to restrict a passenger's head without making use of the passenger's inertia at the collision, surely and rapidly.

Abstract: A vehicle headrest apparatus has a headrest unit that is mounted to an upper end of a seatback. The headrest unit has a head restraining member with a flexible sheet restraining member configured to be tensioned to restrain a passenger's head when a controller detects a rear-end collision. The head restraining member has a vertical support portion facing the head of the passenger and a horizontal support portion substantially perpendicular to an upper part of the vertical support portion. When a rear-end collision occurs, tension is applied to at least the vertical support portion. In some embodiments, the vertical and horizontal support portions are both formed by the flexible sheet restraining member. In other embodiments, only the vertical support portion is partially formed by the flexible sheet restraining member, and the vertical and horizontal support portions are made of a resilient material having an excellent shape-retaining property.

Abstract: A rear end collision sensor is designed to detect the possibility of a rear end collision of a vehicle in advance. Upon detection, a controller drives a seat belt system to restrain the head of a seat occupant toward a headrest of the seat or to straighten the spine of the seat occupant to protect the neck against impending impact.

Abstract: A vehicle headrest apparatus includes a headrest member including a head restraint section to restrain the head of a seat occupant; and a forward move mechanism to move the head restraint section forward in case of a rear end collision of a vehicle. There is further provided an inclining mechanism to incline the head restraint section forward during a forward movement of the head restraint section, by increasing an amount of a forward movement of an upper part of the head restraint section greater than an amount of a forward movement of a lower part of the head restraint section.

Abstract: A seat back frame (25) includes vertical longitudinal frames (27, 29) disposed in a left position and a right position to each other, and transverse frames (31, 33) linking the longitudinal frames (27, 29) to each other, a seatbelt retractor (35) is configured to provide an emergency locking, a seatbelt (5) is linked retractably to the seatbelt retractor (35) and provided with an engagement member (23), a locking member (21) fixed to a longitudinal frame (27) and configured to disengageably lock the engagement member (23), an upper part supporter (47) is provided at an upper part (27a) of the longitudinal frame (27) and configured to support the seatbelt (5) from the seatbelt retractor (35) to return, and the seatbelt retractor (35) and the upper part supporter (49) are arranged to transmit a load acting from the seatbelt (5) on the upper part supporter (47), in a compression direction of the longitudinal frame (27).

Abstract: An active control system is provided with an actuator which controls a noise and/or vibration state of an automotive vehicle, a detector which detects the noise and/or vibration state of the vehicle, and a control unit which receives an output signal of the noise and/or vibration state detector and outputs a signal to control the actuator, the control unit having a neural net which compares a control predicted value based on the output signal with a control target value so that a correction for connection weights in the neural net is carried out on the basis of the comparison result.
