Abstract

It has two side reflectors connected by mutually parallel cross blades. The cross blades (9) consist of resilient material and have V-shaped cross-sections. Arranged in the side reflectors for the cross blades are V-shaped slots (16) which penetrate the cross blades (9) with lateral projections (32, 46), which are provided on their limbs (23) and form hooks (34, 35), directed upwards and downwards, which hold the cross blades (9) on the side reflectors in conjunction with step-shaped shoulders (33) of the cross blades. <IMAGE>
