Frame for an electric heating device, comprising an elastically deformable element

A frame for an electric heating device for heating an air flow circulating inside a ventilation, heating and/or air conditioning installation of a motor vehicle, said frame comprising:

• at least one housing configured to receive at least one heating element, the housing being delimited by a plurality of longitudinal walls forming a longitudinal insertion path for a heating element,
• wherein the insertion path is delimited longitudinally by an end wall that extends on an opposite side from an opening through which it is possible to insert the heating element, an insertion direction being defined from the opening to the end wall, and
• wherein at least one of the longitudinal walls of the housing comprises a displacement reducing element protruding from said wall, the displacement reducing element comprising:
• a ramp extending progressively toward an interior of the housing with respect to the insertion direction, toward the opposite longitudinal wall,
• at least one ridge that is arranged in a continuation of the ramp and forms an apex of the displacement reducing element, the at least one ridge being an innermost part of the displacement reducing element in the housing and extending in the insertion direction of the heating element in the housing, and
• a downstream end comprising a downstream face, the downstream face being configured to link the at least one ridge to the longitudinal wall.
