A door openable in case of structural failure, having a front face (2) and a rear face (3), a vertical hinge side (4) and a latch side (5) from which a latch (6) protrudes for latching said door, characterized in that:

• said door comprises a major door portion (8) bearing said latch (6) and at least one end door portion (9,30) where said at least one end door portion (9,30) is partially enclosed by a first portion of said front face (2) and said rear face (3);
• where said major door portion (8) is enclosed by:
• (a) a second portion of said front face (2) and said rear face (3);
• (b) by said vertical hinge side (4);
• and
• (c) by said latch side (5) of said door;
• wherein said door has a surface (10) inclined downwardly from said front face (2) to said rear face (3) that encloses said major door portion (8), said surface (10) being between said major door portion (8) and said at least one end door portion (9,30), wherein a plurality of energy absorbers are arranged so that said energy absorbers lie along said inclined surface (10), wherein said plurality of energy absorbers are torsion coil springs (11) working in compression, which are housed in respective semi-cylindrical elongated seats (12, 13) formed correspondingly in said major door portion (8) and in said at least one end door portion (9,30), said torsion spring coils (11) being arranged on said inclined surface (10) where an abutment element (14, 15) is provided for each torsion coil spring (11), said abutment element (14,15) being integral with said major door portion (8) and said at least one end door portion (9,30) being positioned at opposite ends of said semi-cylindrical elongated seats (12, 13).
