Awning system comprising - a tubular first roller body with an axis, - a front strip, - a cloth which is connected, on a first side, to the roller body and which is connected, on a second side which is situated opposite the first side, to the front strip, - two elongate guides (2, 3) which extend parallel to each other and which enclose an angle with the horizontal of between 0 and 25 degrees, wherein the front strip extends between the two guides and the front strip is guidable by the guides between a first, non-shading, position situated at first ends of the two guides, in which first position the cloth is wound, at least largely, around the roller body in a first winding direction, and a second, shading, position situated at second ends of the two guides which are situated opposite the respective first ends of the two guides, in which second position the cloth is at least largely unwound from the roller body, - at least one second roller body which is provided concentrically with respect to the first roller body and is rigidly connected to the first roller body for joint rotation about the axis, - at least one elongate flexible transmission member which is connected to the front strip and is wrapped around one of the at least one second roller body, - drive means for rotatably driving the first roller body and the second roller body about the axis, - control means for controlling the drive means, the awning system furthermore comprising at least one locking mechanism which is configured to lock the front strip in the second position, and the control means are configured to actuate the drive means in such a way that the cloth is subjected to tensile stress while the locking mechanism locks the front strip in the second position, characterised in that the at least one locking mechanism comprises a combination of a first locking body and a second locking body which are configured to cooperate in a locking manner, wherein the control means are configured to actuate the drive means in such a way that, during the displacement from the first position to the second position, the front strip, in order to tension the cloth in the second position of the front strip, initially passes the second position to a limited extent and assumes a third position and subsequently moves back to the second position from the third position, wherein the locking mechanism is configured to not yet be active in a locking manner while the front strip passes the second position and to be active in a locking manner when it reaches the third position from the second position, the control means being configured in such a way that, when being displaced from the second position, while the locking mechanism is active, to the first position, to first displace the front strip from the second position in the direction of the third position towards a fourth position, as a result of which displacement, the locking activity of the locking mechanism is cancelled and to subsequently displace the front strip from the fourth position to the first position, the first locking body being provided with a cam track (34, 22, 23, 24, 25) and the second locking body being provided with a cam which cam and cam track are configured to allow the cam to move along at least a first part of the cam track due to the displacement of the front strip from the first position to the second position via the third position, wherein the cam bears against a locking part of the cam track as soon as the front strip has reached the second position from the third position, the cam and the cam track being configured to allow the cam to move from the locking part along at least a second part of the cam track due to the displacement of the front strip from the second position to the first position via the fourth position, wherein the first part of the cam track differs from the second part of the cam track, the cam and/or the cam track is pivotable about a pivot axis and the pivot axis is oriented vertically. - a tubular first roller body with an axis, - a front strip, - a cloth which is connected, on a first side, to the roller body and which is connected, on a second side which is situated opposite the first side, to the front strip, - two elongate guides (2, 3) which extend parallel to each other and which enclose an angle with the horizontal of between 0 and 25 degrees, wherein the front strip extends between the two guides and the front strip is guidable by the guides between a first, non-shading, position situated at first ends of the two guides, in which first position the cloth is wound, at least largely, around the roller body in a first winding direction, and a second, shading, position situated at second ends of the two guides which are situated opposite the respective first ends of the two guides, in which second position the cloth is at least largely unwound from the roller body, - at least one second roller body which is provided concentrically with respect to the first roller body and is rigidly connected to the first roller body for joint rotation about the axis, - at least one elongate flexible transmission member which is connected to the front strip and is wrapped around one of the at least one second roller body, - drive means for rotatably driving the first roller body and the second roller body about the axis, - control means for controlling the drive means,
