Flexible mat null for operational step of job

摘要

PROBLEM TO BE SOLVED: To enhance a vibration absorption and soundproof function and improve the quality of the touch to feet by forming the first rib like a lattice on the reverse side of a mat, and forming the top face of the lattice rib on a placement surface for an operation step. ;SOLUTION: A mat 16 is sized enough to cover the whole of right and left operation step plate materials 15 and a body frame, and the first rib 17 is formed like a lattice on the reverse side of the mat 16. Also, the rib top face of 17a of the rib 17 is formed into a placement surface for an operation step plate materials 15. Furthermore, the second rib 18 lower than the first rib 17 is formed on the reverse side of the mat 16, so as to cross measures made of the first rib 17. According to this construction, the area of the mat 16 corresponding to each measure is deflected down to absorb a driver's weight, when the driver is on board, thereby improving the quality of the touch to his/her feet, and enhancing a vibration absorption and soundproof function.;COPYRIGHT: (C)1997,JPO
