An artificial bait features an overmolded fish attractant sponge and ports through which fish attractant exudes. The bait is comprised of a soft resilient plastic. A container portion of the bait houses the sponge. The container portion includes perforations for fluid communication with the housed sponge. Prior to injection molding, the sponge is a dry compressed cellulose sponge. The sponge is coated with oil prior to injection molding. Pins or blades in the mold assembly position the oil-coated, compressed, cellulose sponge in the container portion of the bait. The pins or blades also define perforations in the container portion for fluid communication with the sponge. The oil coating on the compressed cellulose sponge prevents molten plastic from impregnating the sponge during the injection molding process. The oil coating does not cause the sponge to expand. After manufacture, a water-based fish attractant is introduced into and absorbed by the sponge via the perforations. The fish attractant may be replenished periodically.

A deflector (10) for collecting and guiding harvested tree-fruit is implemented for resilient recovery from collisions with obstacles in the field. The deflector is coupled in cantilever to a boom harvester (4) mounted on a vehicle (2). The harvester has a telescopic boom (8) with a mobile portion (14) terminated by a clamp (6) able to move in horizontal and in vertical translation towards and along a tree trunk (T). The deflector is coupled to the mobile portion for slaved translation with the clamp. Implemented as an array of separate ribs (32) flexibly coupled together and made of flexible elastic plastic material such as fiberglass, the deflector is lightweight and flexes upon collision to resiliently recover shape after the collision. Being lightweight, the cantilever does not destabilize the vehicle. The structure and the materials of construction of the deflector prevent transmission of vibrations generated by the vibrator (12) used to shake the trunk when harvesting.

The subject matter of the invention is a way of shaping anatomically the safety belts of cars, particularly for the use of women, and the devices required for its realization. The essence of this anatomical shaping of a safety belt consists in providing such a form of the belt that it looks like an elongated S, passing between the breasts as well as above and under the bust. For its purpose a safety belt is provided with a shaping strip, which is a flat sleeve made of elastic plastic material in the form of an elongated S, with a rigid material lining, open on the side and closed by means of any kind of fastener, for example a zipper or Velcro. On the upper part of the strip there is a pad protecting the collar-bone and neck against pressure and rubbing. The strip is put on the safety belt, so that it takes the required shape without affecting the structure of the safety belt. The strip can be shifted along the safety belt, adapting it to the height of the passenger. It is practically stable on the safety belt because of its shape, but it can be additionally stabilized by means of a tension pull, the length of which can be adjusted according to the needs of the wearer. The pull can be provided with a clasp, attached to the outer bottom part of the edge of the abdomen part of the safety belt, e.g. by using a clip. Due to different constitutions of the human body there are several hooks for adjusting the position. The tension pull preferably is run perpendicularly to a tangential line of the lower edge of the strip.
