Bathing chair with fixing device

A bathing chair with a fixing device, comprising:

• a front frame and a rear frame, shaped like the inverted letter U, reaching across a bathtub and having horizontal rods which pass over an edge of said bathtub at a distance, said front and rear frames being connected by right and left connecting rods;
• a seat, which is a plate of roughly rectangular shape and is mounted on said horizontal rods;
• a bearing assembly, further comprising several gliding blocks which are connected with said seat on a lower side thereof, keeping a distance thereto, and glide along said horizontal rods, with an opening cut into at least one of said gliding blocks;
• a backrest, connected to said seat by two L-shaped link rods with horizontal extensions which are fastened to said gliding blocks of said bearing assembly, enabling said seat to glide along said horizontal rods;
• a handle, which is a rod shaped like the inverted letter U and fastened to said front and rear frame rods at left ends thereof, reaching higher than said seat;
• and
• a fixing device, further comprising
• two lugs, each having a hole and aligned on two sides of said gliding block,
• a blocking piece, made of elastic material, having an excentric hole, and placed between said two lugs,
• an axis, passing through said holes of said two lugs and said excentric hole of said blocking piece,
• and an arm, attached to a periphery of said blocking piece;
• wherein, for fixing a position of said seat, said arm is shifted, turning said blocking piece and causing said blocking piece to pass through said opening and to press against one of said horizontal rods, so that said seat is by friction prevented from moving.
