Accessory with a tiltable accessory support and a locking system releasable by means of a tiltable actuator button

An accessory (100) that comprises:

• a façade plate (120) presenting an opening (124);
• an accessory support (110) that is mounted to tilt through said opening between a lowered position in which the accessory support extends below the façade plate, and a raised position in which a major portion thereof extends above the façade plate;
• a locking system (300) that comprises firstly at least one locking arm (310) that is movable between a locking position in which a blocking portion (311) of said locking arm bears against a blocking surface (118) of the accessory support (110), and a release position in which said blocking portion (311) is spaced apart from said blocking surface (118), and secondly an actuator button (140), distinct from the accessory support (110), that co-operates with said locking arm so as to cause the locking arm (310) to move, the actuator button being tiltable about a tilt axis (X1) that extends parallel to the mean plane (P) of said façade plate (120);
• wherein said locking arm (310) is pivotable about a pivot axis (Z) that is perpendicular to said tilt axis (X1) of the actuator button (140), and wherein resilient return means (320) are provided that continuously urge said locking arm (310) into the locking position.
