Patent number: 7604081Abstract: A vehicle passenger restricting system is provided to restrict passenger movement so that a space between a passenger's head and the ceiling of the vehicle is effectively enlarged when a rollover condition occurs. The vehicle passenger restricting system has a passenger seat, a rollover detector, a seat tilting device and a controller. The rollover detector detects a vehicle rollover condition. The vehicle passenger restricting device restricts passenger movement on the passenger seat. The seat tilting device tilts the seat in a backward direction. The controller activates the seat tilting device to recline the seat backwards when the rollover detector detects the vehicle rollover condition exists.

Patent number: 7185728Abstract: A vehicle front end structure is configured to handle a front collision by using one or more inflatable bags to bear the collision load and produce a stable reaction force. The front inflatable bag is provided in a region where a colliding object can contact the front end of a vehicle body and configured such that it can deploy and inflate into a wall surface-like shape immediately before a collision. As a result, the collision load of a front collision can be absorbed efficiently. Additionally, since the inflated front inflatable bag serves to bear the collision load as a surface, it can generate a stable reaction force irregardless of the angle at which the collision load is imparted, the size of the colliding object, or size of the overlap ratio.Type: GrantFiled: December 28, 2004Date of Patent: March 6, 2007Assignee: Nissan Motor Co., Ltd.Inventors: Masashi Makita, Chinmoy Pal

Patent number: 7008007Abstract: A vehicle body end structure has a longitudinal frame member connected to a transverse frame member by curved parts to disperse the load when the vehicle undergoes an end (rear or front) collision. In particular, wedge-shaped open spaces exist between the interior surfaces of the transverse frame member and the corresponding wall surfaces of the curved parts that face the interior surfaces. Consequently, when the vehicle undergoes an end collision, the inward collapsing of the transverse frame member causes the curved parts to gradually undergo bending deformation while being folded over such that the curved parts touch against the transverse frame member. Deformation control structures are provided on the curved parts to prevent localized stress concentration from occurring and enable the curved parts to deform in a stable manner. Thus, the curved parts are prevented from undergoing acute bending and the input load is absorbed more efficiently.Type: GrantFiled: July 27, 2004Date of Patent: March 7, 2006Assignee: Nissan Motors Co., Ltd.Inventors: Masashi Makita, Chinmoy Pal

Patent number: 6948767Abstract: 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.Type: GrantFiled: January 29, 2004Date of Patent: September 27, 2005Assignee: Nissan Motor Co., Ltd.Inventors: Masashi Makita, Chinmoy Pal
