Definitions

  • the invention relates to a lock arrangement according to the preamble of Claim 1.
  • the invention is based on a different object. If you look at that preferred application of the invention, namely as a lock arrangement for a motor vehicle front hood, so one is interested in the impact of a pedestrian on the Front hood designed to act as a deformation element. There are, therefore, related ones Proposals to make the actual bonnet locally compliant, so that especially in the usual impact area of a pedestrian's head on the hood a deformation of the hood associated with energy conversion and thus a certain one Relief of the pedestrian head against high delays take place.
  • the critical point is that usually provided at the front end of the front hood Lock. It must be designed so that during normal operation of the vehicle Occurring closing forces of the hood of the striker not as far into the The actual lock containing the catch can penetrate because of the danger of Damage to the hood would be associated with the normal closing of the same. Therefore, the construction of the lock arrangement must be designed so that, largely regardless of the amount of closing force exerted on the hood, the rotary latch is pivoted into a defined locking position, but not beyond this. With others Words: one for the specified preferred and other similar applications suitable lock arrangement is relatively hard in the locked state of the hood, so that it is obviously unsuitable for the goal of pedestrian protection.
  • the invention has for its object to a generic lock assembly create, on the one hand in terms of operational requirements - defined rest position the catch - is optimized, but on the other hand also the requirements regarding the Pedestrian safety is enough.
  • the protrudes Stop for example, in the swivel path of the rotary latch or one rigid with it connected component of the lock assembly, so that the catch is not above its Rest position can be pivoted, the maximum closing forces that experience has shown that it can be exercised on the hood, on which the design is based.
  • a linearly guided mass-related stop may be provided, which by means of a compression spring during the normal operation of the vehicle is secured in the swivel path of the rotary latch while the Inertial forces counter the action of the spring in the event of a crash Move the swivel path of the rotary latch.
  • a blasting device that him in Crash trap removed as it were.
  • such explosive devices can be found in the frame use of safety steering columns, whereby detonations between the explosions then telescopic steering column components are eliminated.
  • the stop 6 which is in the way of the lower edge of the Rotary latch 2 when swiveling the same beyond its locking position (FIG. 2), that is down, lies.
  • the lock arrangement as in the length of the gap 4 in Housing recognizable for a further movement of the striker 1 relative to Lock housing designed in the downward direction, namely by a so-called Crash stroke 7, but in the operating modes of Figures 1 and 2, the stop 6 prevents one such movement so that - except for a narrow gap between parts 2 and 6 - when the catch 2 is in the locked position, this involves a further pivoting movement is hindered clockwise by the stop 6. This is the above Condition met that regardless of the amount of exercise applied to the hood Closing force must always be the same locking position of the rotary latch 2.
  • the stop 6 is now as by his partial representation indicated by broken lines, in Figure 3 to the rear this further swivel path of the catch 2 is pulled out, shifted or pyrotechnically blown away, so that he the movement of the catch 2 with the striker 1 from the Position according to Figure 2 (locking position of the rotary latch) corresponding to the crash stroke 7 in the relative position of the different parts according to Figure 3 can not hinder.
  • the Crashhub 7 can either only be used to achieve compliance or as a deformation path be exploited, during the transfer of kinetic energy in deformation work on any components of the castle or Vehicle takes place, as this is a sign of a deformation path.
  • the invention achieves the defined task with simple means created two contradictory requirements, namely stiffness and Compliance, depending on the operating conditions - normal operation, Crash operation - to be fulfilled.
