Embodiment Construction

[0028] refer to figure 1 , shows a vehicle 4 having a body 5 with one or more closure panels 6. The closure panel 6 is connected to the vehicle body 5 via one or more panel operating components 8 such as, but not limited to, hinges 98 and / or latches 100 (eg, once closed, The closure panel 6 is kept in the closed position or the closure panel 6 is kept in the open position once opened). It should also be appreciated that the hinge 98 may be configured as a biased hinge that may be configured to bias the closure panel 6 toward the open position and / or toward the closed position. Furthermore, the panel operating part 8 may be configured as a lift assist system, for example used in a rear lift gate system, which includes one or more struts (not shown). The closure panel 6 may have a cooperating latch member 96 (e.g., a striker) mounted thereon for coupling with a corresponding panel operating member 8 (e.g., a latch) mounted on the vehicle body 5. Alternatively, the panel opera...

Abstract

The invention provides a latch assembly for providing travel of a closure panel of a vehicle away from a latch during a collision event. The latch assembly compromises: a mounting plate of the latch for mounting a set of latch components thereon including a ratchet coupled to a pawl for retaining and releasing a mating latch component with respect to a slot of the latch, the mating latch componentmounted to the closure panel, the latch components further including a secondary catch, the mounting plate connected to a body of the vehicle; a support plate coupled to the mounting plate by a support connector, the support connector providing a sliding connection between the support plate and the mounting plate along an axis; a blocking member mounted to one of the support plate and the mounting plate, such that engagement of the blocking member limits relative displacement between the support plate and the mounting plate along the axis; an actuation system mounted on the support plate, theactuation system for moving by the travel the closure panel between a primary latched position and a secondary latched position during actuation of the actuation system; wherein disengagement of theblocking member subsequent to the actuation of the actuation system provides for the relative displacement between the support plate and the mounting plate along the axis opposite to the direction ofthe travel of the closure panel..

Description

technical field [0001] The present disclosure relates to vehicle safety systems. Background technique [0002] The automotive industry is trying to better protect pedestrians from head-on collisions with vehicles. When a car hits a pedestrian in a front-end collision, the pedestrian is thrown up and lands on the vehicle's front hood and / or windshield. To improve the severity of the impact, and in particular to prevent a person's head from striking the engine block or other hard point located directly under the front hood, it is necessary to actively align the front hood with the engine block whenever a front-end collision is detected. spaced apart. In particular, when a front-end collision is detected by the crash sensors, it is desirable to move the front hood from a first aerodynamic position to a second position within a very short period of time (eg, in milliseconds), during the first aerodynamic In the dynamic position, the front hood is typically positioned very clo...
