Abstract
A lock for a door of a motor vehicle is provided having: a closing mechanism designed for coupling with a lock striker along a direction of relative coupling; a supporting body of the closing mechanism presenting a housing seat for an engagement portion of the lock striker; and elastically compliant arrest means delimiting the housing seat at least in the aforesaid direction of relative coupling in order to define a damped arrest of the engagement portion of the lock striker. The arrest means are coated on their surface, in the area of interaction with the engagement portion of the lock striker by a rigid protective shield.
Claims7
A lock (1) for a door of a motor vehicle comprising:
- a closing mechanism (6) designed for coupling with a lock striker (2) along a direction (b) of relative coupling;
- a supporting body (4) of said closing mechanism (6) having a housing seat (5) for an engagement portion (3) of said lock striker (2);
- said housing seat (5) having an entry area (11) for said engagement portion (3) and being delimited:
- laterally, by a pair of faced ramps (15) diverging with respect to one another towards said entry area (11), and
- at an end opposite to said entry area (11), by a bottom wall (12) orthogonal to said direction (B) of relative coupling;
- elastically compliant arrest means (30) coupled to said bottom wall (12) to delimit said housing seat (5) in said direction (B) of relative coupling in order to define damped arrest of said engagement portion (3) of said lock striker (2);
- said arrest means (30) being coated on their surface, in the area of interaction with said engagement portion (3) of said lock striker (2), by a rigid protective shield (40);
- characterized in that said shield (40) is carried by said arrest means (30) and is distinct from said ramps (15).
The lock according to any one of the preceding claims, characterized in that said shield (40) has, in the area of interaction with said engagement portion (3) of said lock striker (2), a surface coating of ceramic material.
