La première base fixe (3.31) électromagnétique, obtenue par fléchissement d'une plaque métallique, présente, en son milieu, une base plate (3.31A) et, sur son extrémité, deux languettes repliées (3.31B). La première base fixe (3.31) est fixée horizontalement sur la base inférieure (3.4), le corps magnétique (3.2) est fixé sur un côté de la base plate (3.31A) de la première base fixe (3.31) et l'élément d'étirement (3.1) est placé sur l'autre côté de la base plate (3.31A). Entre le corps magnétique (3.2) et l'élément d'attraction (3.11) vient la base plate (3.31A) formant par intervalle moyennant l'attraction mutuelle magnétique un ensemble de liaison attiré par une force extérieure. Lorsque la force de traction atteint la force d'attraction magnétique, l'ensemble de liaison magnétique se divise de manière à libérer la tension. L'utilisation du lit pour étirement d'un corps vertébral de ce dispositif de limitation de force magnétique (3) requiert un cadre de lit (1), un dispositif d'entraînement électrique (2) sur le côté inférieur de la table (1.1) et une bande d'étirement (4), le dispositif de limitation de force magnétique (3) et la bande d'étirement (4) étant assemblés. La force d'attraction magnétique du dispositif de limitation de force magnétique (3) est une force d'étirement sûre. Lorsque l'effort de traction atteint la force d'étirement sûre, l'ensemble de liaison par étirement se divise de manière à libérer la tension, et ce, afin de protéger la personne recevant le massage.
