Door for a motor vehicle

A door (4, 4′, 4″) for a motor vehicle (1) comprising:

• a lock (25) available in a closed configuration, in which it prevents said door (4, 4′, 4″) from shifting from a closed position to an open position, and in an open configuration, in which it allows said door (4, 4′, 4″) to shift from said closed position to said open position;
• said door (4, 4′, 4″) allowing, in use, access to a passenger compartment (3) of said motor vehicle (1) in said open position and forbidding in use, access to said passenger compartment (3) in said closed position;
• a support body (20) comprising, in turn, a first portion (50) and a second portion (51), which are integral to one another, when said door (4, 4′, 4″) is, in use, in a normal operating condition;
• a ratchet (22) supported by said first portion (50) of said support body (20) and capable of being operated to determine the shifting of said lock (25) from said closed configuration to said open configuration;
• and
• a Bowden cable (31), which is interposed between said ratchet (22) and said lock (25), can be operated by said ratchet (22) and is at least partly housed in a first seat (45) defined by said first portion (50) of said support body (20);
• characterized in that said support body (20) comprises a preferential breaking area (60) designed to break, in use, due a predetermined load in case of impact of said door (4, 4′, 4″), so as to determine the separation of said first portion (50) carrying said Bowden cable (31) and said ratchet (22) from said second portion (51) of the support body (20).
