Information device intended to equip a roadway

Abstract

The invention relates to an information device (1) comprising a lower part (2) extending along a general extension axis (A1) and equipped with an inflatable structure (8) comprising a first wall (9) and a second wall (10). The first wall (9) has a first transverse wall (9a) substantially orthogonal to the general extension axis (A1) and a first cylindrical radial wall (9b) whose axis of revolution coincides with the general extension axis (A1). The second wall (10) has a second transverse wall (10a) substantially orthogonal to the general extension axis (A1) and a second cylindrical radial wall (10b) whose axis of revolution coincides with the general extension axis (A1). The first wall (9) and the second wall (10) have, in the operating position, a U-shaped profile in a cross-section formed along a cutting plane (P1) comprising the general extension axis (A1).
