Glove box for a dashboard of a motor vehicle; glove box comprising: a container mountable on the dashboard of the motor vehicle; said container being provided with an opening for loading/unloading the objects; covering means of said opening ; said covering means being hinged to said container by hinge means ; and elastic energy-accumulating means (50; 550) mechanically coupled to said covering means ; said elastic energy-accumulating means being elastically loaded due to the movement of said covering means when opening said opening ; said elastic energy-accumulating means comprising an elastic assembly having a Young's modulus of elasticity variable according to the deformation of said elastic assembly ; said elastic assembly comprising a first spring and a second spring ; said first spring comprising a first end fastened to a wall and a second end to which a first end of pulling means is fastened; a first portion (60*) of said pulling means extending at least partially freely in said second spring ; a second end of said pulling means being fastened to said covering means ; said second spring comprising a first free end and a second end resting on an abutment element ; characterized in that , when a user opens the glove box by rotating the covering means about the hinge means , said first spring is elongated by said pulling means and the second end of said first spring comes to rest on the first end of said second spring , so that the first and second springs become in series; as the covering means opens further, the pulling means increasingly pulls the second end of said first spring , so that said first spring starts compressing said second spring , thus deforming it. a container mountable on the dashboard of the motor vehicle; said container being provided with an opening for loading/unloading the objects; covering means of said opening ; said covering means being hinged to said container by hinge means ; and elastic energy-accumulating means (50; 550) mechanically coupled to said covering means ; said elastic energy-accumulating means being elastically loaded due to the movement of said covering means when opening said opening ; said elastic energy-accumulating means comprising an elastic assembly having a Young's modulus of elasticity variable according to the deformation of said elastic assembly ; said elastic assembly comprising a first spring and a second spring ; said first spring comprising a first end fastened to a wall and a second end to which a first end of pulling means is fastened; a first portion (60*) of said pulling means extending at least partially freely in said second spring ; a second end of said pulling means being fastened to said covering means ; said second spring comprising a first free end and a second end resting on an abutment element ; characterized in that , when a user opens the glove box by rotating the covering means about the hinge means , said first spring is elongated by said pulling means and the second end of said first spring comes to rest on the first end of said second spring , so that the first and second springs become in series; as the covering means opens further, the pulling means increasingly pulls the second end of said first spring , so that said first spring starts compressing said second spring , thus deforming it. <EOS>
