Abstract

Shoulder support for a motor includes: a back-plate which is adapted for being associated with the back of an operator through shoulder straps and includes a shaped body to contact with the back of the operator to which a frame is fixed, the frame being substantially L-shaped and includes a first portion, fixed to the back-plate, and a second portion undercut with respect to the first portion and comprising a through opening with substantially vertical through axis, the motor being connected at the top the of second portion; a connection body adapted for being rigidly connected to the motor; and a resilient support element adapted for connecting the connection body to the frame in a floating manner inside a seat defined by the through opening. The resilient support element includes a plurality of springs, having axes, which lay on a plane adapted for being arranged transversally to a vertical direction.

Claims

1. Shoulder support (1) for a motor (2) comprising:

a back-plate (10) which is adapted for being associated with the back of an operator through shoulder straps (11) and comprises a shaped body to come into contact with the back of the operator to which a frame (12) is fixed, said frame being substantially L-shaped and comprising a first portion (120), fixed to the back-plate (10), and a second portion (121) undercut with respect to the first portion (120) and comprising a through opening (122) with substantially vertical through axis, the motor (2) being connected at the top the of second portion (121),

a connection body (14) adapted for being rigidly connected to the motor (2) and

a resilient support element adapted for connecting the connection body (14) to the frame (12) in a floating manner inside a seat defined by the through opening (122),

wherein the resilient support element comprises a plurality of springs (16), having axes, which lay on a plane that is adapted for being arranged transversally to a vertical direction, and

wherein the shoulder support (1) comprises an abutment element (17) configured to limit an oscillation of the connection body (14) with respect to the frame (12) along a direction transversal to the axes of the springs (16).

2. The shoulder support (1) according to claim 1, wherein the abutment element (17) is configured to limit the oscillation of the connection body (14) with respect to a substantially vertical direction.

3. The shoulder support (1) according to claim 1, wherein the frame (12) is L-shaped and comprises a first portion (120) and a second portion (121) undercut with respect to the first portion (120), and wherein the connection body (14) and the abutment element (17) are connected to the second portion (121).

4. The shoulder support (1) according to claim 3, wherein the second portion (121) of the frame (12) comprises a through opening (122) and wherein the connection body (14) is vertically aligned with the through opening (122), the abutment element (17) being configured to at least partially block the through opening (122).

5. The shoulder support (1) according to claim 3, wherein the abutment element (17) is fixed to the second portion (121) of the frame (12) on an opposite side with respect to the motor (2).

6. The shoulder support (1) according to claim 1, wherein the abutment element (17) is arranged at a distance from the connection body (14) between 3 mm and 6 mm.

7. The shoulder support (1) according to claim 1, wherein the abutment element comprises a plate (17) fixed to the frame (12).

8. The shoulder support (1) according to claim 7, wherein the plate (17) is equipped with a central hole (171).

9. The shoulder support (1) according to claim 1, wherein the plurality of springs (16) are arranged with radial axis with respect to the connection body (14) itself and each spring (16) comprises a first end fixed to the frame (12) and a second end fixed to the connection body (14).

10. A power group comprising a shoulder support (1) according to claim 1 and a motor (2) connected to the connection body (14) of the shoulder support (1).
