Definitions
- the invention relates to a lock arrangement according to the preamble of Patent claim 1.
- the invention is based on a different kind of task.
- a lock assembly for a motor vehicle front hood so one is interested in the impact of a pedestrian on the Front hood to interpret these acting as a deformation member.
- Suggestions to make the actual bonnet locally yielding so that especially in the usual service area of the head of a pedestrian on the hood a deformation associated with energy conversion of the hood and thus a certain Relief of the pedestrian's head to take place against high delays.
- a concerning this relief of the body of the pedestrian from high deceleration forces critical point is usually provided at the front end of the bonnet Lock. It must be designed so that when in normal operation of the vehicle Occurring closing forces of the hood of the striker not arbitrarily far in the Rotary latch containing actual lock can penetrate, since thus the risk of Damage to the hood would be connected even during normal closing of the same. Therefore, the construction of the lock assembly must be designed so that, largely regardless of the amount of force exerted on the hood respectively closing force, the catch is pivoted in a defined detent position, but not beyond this. With others Words: one for the specified preferred and other similar stored applications suitable lock assembly is relatively hard in the locked state of the hood, so they obviously unsuitable for the purpose of pedestrian protection.
- the invention has the object of providing a generic lock arrangement create, on the one hand, in terms of operating requirements - defined detent position the catch - is optimized, on the other hand, but also the requirements in terms of Pedestrian safety is sufficient.
- the towers Stop for example, in the pivoting of the catch or a rigid with this connected component of the lock assembly, so that the catch is not over her Detent position can be pivoted out, with the maximum closing forces, the Experience has shown that they are applied to the bonnet, which are the basis for the interpretation.
- the expert knows a whole series of Possibilities: For example, an electric drive for the relocation of the Be provided stop, the release of the drive by a se known crash or pre-crash sensor can be done. During the crash sensor immediately detects the vehicle's contact with a foreign object, says the Pre-crash sensor ahead of imminent collision. For relocation the stop from the track of the catch or the rotatable with her connected component but also the inertia can be exploited, as to is known from the prior art discussed at the beginning.
- a linear guided mass-afflicted stop be provided, which by means of a compression spring during the normal operation of the vehicle is secured in the pivoting path of the rotary latch, while the Inertia forces against the action of the spring stop in a crash from the Move pivoting path of the rotary latch.
- a crash or pre-crash sensor may be provided for the stop a Absprengvorlegi him in the Crash trap as it were removed.
- Lock arrangement limited. In all cases, it is a front hood a motor vehicle associated lock assembly, which is viewed from the front.
- the stopper 6 is now, as by his partially indicated by broken lines, in Figure 3 to the rear withdrawn from this further pivoting of the catch 2, relocated or pyrotechnic weggesprengt so that he the movement of the catch 2 with the striker 1 from the Position according to Figure 2 (detent position of the catch) according to the crash stroke 7 in the Relative position of the various parts according to Figure 3 can not interfere.
- the crash stroke 7 can either only to achieve a compliance or as a deformation path be exploited during its deferred implementation of kinetic energy in deformation work on any components of the castle or the Vehicle takes place, as this is a characteristic of a Deformationsweg.
