Definitions

  • Safety device for a motor vehicle with a rotary latch and a pre-locking position and a main latching position
  • the invention relates to a safety device for a motor vehicle, which has a lock holder, a pawl and a rotary latch, wherein the rotary latch has a load arm, a catching arm, an opening direction of rotation, a closing direction of rotation, a pre-locking position and a main latching position.
  • Such a safety device is known from DE 10 2007 045 716 A1.
  • a rotary latch with a load arm and a catching arm and a detent position is described, wherein a pawl engages around the catch in the detent position of the rotary latch on the load arm.

  • a realization of a Vorrastsannon and a main detent position of a rotary latch according to DE 199 37 405 B4 with a pawl and an additional latch also has the disadvantage of an additional component and thus an increased total weight of the safety device.
  • An increased total weight of the safety device adversely affects consumption of a motor vehicle in which the safety device is installed.
  • Object of the present invention is therefore to provide a safety device according to the preamble, in which a total weight of the safety device is reduced.
  • a safety device for a motor vehicle which has a lock holder, a pawl and a rotary latch, wherein the catch a load arm, a tentacle, an opening direction of rotation , has a closing direction of rotation, a Vorrastsannon and a Hauptastastwolf and the Pawl is engaged in the Vorrastsander the catch on the catching arm and in the main latching position on the load arm.

  • the Vorrastsander the catch is used to catch the front cover, a door or a flap in an installed state of the safety device when the main latching position of the catch is not reached when closing.
  • the pre-ratchet division of the rotary latch serves to provide an intermediate position when the safety device is opened between the locking position of the safety device and an open position of the safety device in which the lock holder is released in the opening movement direction.
  • the tentacle and the load arm form a fork-shaped inlet mouth of the rotary latch, which receives the lock holder during a closing operation of the rotary latch.
  • the tentacle and the load arm each have a head portion, wherein the two head portions are advantageously the furthest away from a rotational axis of the rotary latch portions of the rotary latch.
  • the two head areas form an opening of the inlet mouth into which the lock holder enters during the closing process of the rotary latch.
  • the head regions may preferably each extend up to a fifth of a length of the catching arm or of the load arm from the respective end of the catching arm or the load arm up to the axis of rotation of the rotary catch.
  • the load arm and the tentacle are preferably at least partially arcuate in order to allow guiding of the lock holder within the inlet mouth during a closing movement of the rotary latch.
  • a particularly advantageous embodiment of the invention provides that the head region of the catching arm has a bend with a latching surface in the direction of the opening direction of rotation.

In the main locking position of the catch, the locking lug of the pawl is located on the latching surface, wherein the latching nose engages around the bend of the load arm and the pawl assumes the blocking position.
  • the combination of these two embodiments makes it possible that the pawl can be latched directly in the region of the opening of the inlet mouth both in the Vorrastsannon and in the main latching position of the rotary latch and secures the rotary latch against rotation in the opening direction.
  • a Rotary latch spring of the safety device acts on the rotary latch in the opening direction and presses the respective locking surfaces in the opening direction against the locking lug of the pawl.

  • the safety device has a delay mechanism for delaying the rotary latch.
  • the delay mechanism ensures upon rotation of the rotary latch in the opening direction of rotation starting from the main latching position latching of the rotary latch in the Vorrastsander. In this embodiment, a longer period is available within which the pawl can reach the blocking position before the catch assumes the Vorrastsannon.
  • the advantage of this variant is that can be dispensed with an adjustment of the spring stiffness of the pawl spring to the spring stiffness of the rotary latch spring and still can be ensured in a rotation of the catch in the opening direction starting from the main latching position locking the catch in the Vorrastsannon.
  • a pawl spring can be dimensioned smaller, which additionally reduces the total weight of the safety device.
  • the Delay mechanism may for example be designed in the form of a friction surface, which brakes the catch before reaching the Vorrastsannon.
  • the deceleration mechanism has a stop surface for stopping the rotary latch. The stop surface may be arranged for example on a boom of the pawl and cooperate with the bend of the tentacle.
  • the stop surface on the tentacle preferably at the bend of the tentacle, be arranged and cooperate with the boom of the pawl.

  • a slope of the first active surface is different from a gradient of the second active surface, wherein when sliding the mating surface of the catching arm on the first active surface, a different relative speed of the catching arm with respect to the pawl in comparison to a relative speed of the load arm with respect to the pawl when sliding the counter surface of the load arm is effected on the second active surface.
  • the rotary latch spring is designed as a spiral spring. This can in particular a narrower design of the safety device with respect to a safety device in which the rotary latch spring is designed as a leg spring allow.
  • the design of the rotary latch spring as a spiral spring can simplify in particular a common mounting of the rotary latch and the rotary latch spring on a common axis of rotation, said common storage represents another possible embodiment of the safety device.
  • the narrower construction of the rotary latch spring as a coil spring against a leg spring advantageous because bearings of a pair of bearings for the common axis of rotation can be arranged closer to each other and thereby the axis of rotation can be made shorter and a higher load of the axis of rotation is possible to more than one component to store.
  • the rotary latch spring has a leg with at least one section, wherein the section in the main latching position has a nearly horizontal orientation and rests against the lock holder. Alignment is dictated by a connecting line between a beginning and an end of the section, the section extending along the leg.

In the installed state, an exactly horizontal line runs parallel to a vehicle longitudinal axis of the motor vehicle. Almost horizontal means that the connecting line includes an angle of at least less than 20 degrees, preferably less than 15 degrees, with the vehicle longitudinal axis.
  • the horizontal portion of the leg adjacent to a turn of the rotary latch spring can cause an initial force acting from the leg to the lock retainer to be oriented nearly vertically, in particular perpendicular to the vehicle longitudinal axis, at an initial rotation of the leg and nearly the entire normal force acts against a transmitted via the lock holder weight.
  • This may allow the rotary latch spring for driving the rotary latch in the opening direction of rotation and preferably for ejecting the lock holder can be made smaller.
