2. An aid as defined by claim 1 , wherein the end profile ( 5 ) has a middle bar ( 5 c ) and two longitudinal bars ( 5 a , 5 b ) joined to it in the shape of a U, and the longitudinal bars ( 5 a , 5 b ) are provided on their ends with the second positioning means ( 15 , 15 a ).
3. An aid as defined by claim 1 , wherein the lateral parts ( 4 ) and the end profile ( 5 ) comprise shaped sheet-metal parts bent into the shape of a U.
4. An aid as defined by claim 1 , wherein the bracing strut ( 6 ) comprises a flat bar.
5. An aid as defined by claim 1 , wherein the positioning means ( 14 , 14 a , 15 , 15 a ; 25 , 25 a , 25 b , 26 ) are produced by laser cutting.
6. An aid as defined by claim 1 , wherein at least one of the lateral parts ( 4 ) and the end profile ( 5 ) are provided on their ends with angled securing plates ( 18 ) for securing each other.
7. An aid as defined by claim 6 , wherein the securing plates ( 18 ) are provided with screw holes ( 20 ).
8. An aid as defined by claim 1 , wherein a base that covers the interior of the frame ( 3 ) is secured to at least one of the undersides of the lateral parts ( 4 ) and of the end profile ( 5 ).
9. An aid for vehicles for carrying passengers, selected from the group consisting of a boarding aid, an entry aid, and both, having a rectangular frame ( 3 ) that has two parallel lateral parts ( 4 ), which are solidly joined together at rear ends by an end profile ( 5 ) and, in a region spaced apart from it, by at least one bracing strut ( 6 ), and having a step plate ( 2 ), supported movably on the lateral parts ( 4 ), wherein the lateral parts ( 4 ), the end profile ( 5 ), and the bracing strut ( 6 ) are provided with positioning means ( 14 , 14 a , 15 , 15 a ; 25 , 25 a , 25 b , 26 ) that engage one another in form-locking fashion, wherein a base that covers the interior of the frame ( 3 ) is secured to at least one of the undersides of the lateral parts ( 4 ) and of the end profile ( 5 ), wherein the frame ( 3 ), in a rear region, has a servicing hatch ( 30 ) that can be pivoted downward.
