Each lateral piece (122A,122B) has a base element (1221) which extends through a portion of the length of the support shaft and attaches to the bottom of the middle piece and to corresponding lateral piece of the support shaft. A part of the support shaft and a part of a mounting part (12) are positively connected with each other so that the support shaft is held on the base element.</p> |
