Problems solved by technology

Therefore the latch will be weakened and worn out prematurely
Also, the extra pressure required to untangle is difficult to measure, and the user does not have time to adjust the pressure he is applying with his fingers when untangle occurs
As a result, in response to this extra pressure, the catch bolt can pivot suddenly, which can cause damage to the side pin and render the latch unusable
Additionally, between the two locked positions, the side pins are in continuous contact with the side walls of the anchoring element, creating friction that makes it more difficult to move the latch from one position to the other
Finally, this latch consists of several parts, making it difficult to manufacture, assemble and use

Embodiment Construction

[0024] Referring now to the drawings, the cover 1 according to the invention is designed for closing an aperture 101 provided in a support 100 such as an engine block. The cover 1 comprises a housing 2 , fastening tabs 3 and a latch 4 .

[0025] The housing 2 comprises an integral plate 20 from which extends a skirt 21 substantially perpendicular to the plate 20 and to be received in the aperture 101 . Seen from above, the plate 20 has a substantially trapezoidal shape. The plate 20 has a downwardly directed cavity forming a raised portion 22 on its upper surface and a receiving space (not visible) below its lower surface. The cavity can receive, for example, a projection of a sensor (not shown) arranged in the receiving space. The receiving space opens laterally to the plate 20 via a channel 24 open downwards, capable of receiving, for example, supply and / or communication cables connecting the engine speed sensor with the electronic entity of the motor vehicle. The channel...

Abstract

The invention relates to a cover (1) including a shell (20) for closing an opening (101) and a latch (4) pivoting between "unlocked" and "locked" positions in which said latch respectively does not or does hinder the mobility of the cover (1) with respect to the support (100), the cover (1) comprising stationary stops (51) and laterally flexible latching lugs (44) provided to prevent the passage without bending of the latching lugs (44) and to latch the latch (4) in the "locked" position, the clearances (50) allowing the passage of the bent latching lugs (44) and of the unlatching wings (45) connected to the latching lugs (44) and capable of being biased laterally by hand to bend the latching lugs (44) and thus allow the unlatching of the latch (4) from the "locked" position thereof. Said cover (1) is suitable for closing an opening (101) provided in a motor block for accommodating an electronic sensor therein.

Description

technical field [0001] The invention generally relates to a cover comprising a housing provided with a first locking edge for resting on the edge of an aperture provided in a support so that the housing closes the the aperture; the cover includes at least one latch provided with a second locking edge and adapted to move about a pivot axis between an unlocked position and a locked position, at least one latch allowing the cover to The member moves relative to the support member, and the second locking edge cooperates with the first locking edge in the locked position to lock the cover member on the support member; a latch device with a positive locking lug and at least one fixed stop, one of the fixed stop and the flexible locking lug is arranged on the housing, and the other of them is arranged on the latch, And the two can cooperate to prevent the catch lug from moving from the unlocked position to the locked position without bending and can snap the latch in the locked posi...
