Each fish mouth portion 24 comprises, as shown in FIGS. 2 to 4, a substantially U-shaped portion with a upper and a lower 'legs 26 and 28, which are connected to one another by an intermediate piece 30, which extends from the straight section 22 extends downward. The upper leg 26 forms a torsion bar that is shorter than the Is a torsion bar which is formed by the lower leg 28. Each fish mouth section also includes a V-shaped one Part with a torsion bar 32 and an upper one, and one lower spacer rod 34 and 36, which are from opposite. Extend the ends of the torsion bar 32 away. The upper spacer rod 34 is connected in one piece to the lower leg 28. A U-shaped section is connected in one piece to the spacer rod 36, consisting of a torsion bar 38, a connecting piece 40 and an end section 42 which is used to support of the fish mouth portion 24 is used. In detail, the spring core comprises one. Wooden frame, consisting of the side parts. 44f the end portions 46 and those extending in the longitudinal direction Parts 48. The Fischmaulabschn.itte 24 are supported on the frame 44 in that the torsion bar 38, the Connector 40 and the end portion 42 on part of the Sitting wooden frame, with at least the torsion bar 30 am Wooden frame is pinned or otherwise attached to it. As an alternative, the end section 42 can also be on the wooden frame pinned or otherwise attached to it.
