The present invention relates to a safety chair (1) for a free fall lifeboat. The chair includes a body shell (12) with a seat portion and a concave back portion (14) with an upper part and a lower part. The seat includes a seat belt system (2) with two shoulder straps (25, 26), a head support assembly and a slide arrangement attaching the upper parts of the at least two shoulder straps (25, 26) and the head support assembly to the concave back portion (14). The upper parts of the at least two shoulder straps (25, 26) and the head support assembly are adjustable along the concave back portion (14) between an upper position towards the upper part of the concave back portion (14) and a lower position towards the lower part of the concave back portion (14). Furthermore, the invention relates to a chair body shell (12) for a safety chair (1)and an assembly of at least four safety chairs (1) in at least two staggered lines.

The present invention relates to an apparatus for attaching a life boat to a lifting sling (1) The invention comprises a first attachment element (5a) and a second attachment element (5b) opposing the first attachment element; a first guiding foundation (7) fixed to the first attachment element (5a), wherein the first guiding foundation (7) includes a first guiding area (17) for guiding the lifting sling (1) in a direction away from the first attachment element (5a) and a first receiving recess(14); a second guiding foundation (8) fixed to the second attachment element (5b), wherein the second guiding foundation (8) includes a second guiding area (18) for guiding the lifting sling (1) in a direction away from the second attachment element (5b) and a second receiving recess (13); a lifting sling latch member (9) pivoted to the second guiding foundation for allowing the latch member to pivot between a first position wherein the latch member (9) is seated in the first receiving recess (14) and in the second receiving recess (13), and a second position away from the first guiding foundation (7), whereby said lifting sling (1) may be attached to the apparatus in said first position of said lifting sling latch member (9) and released from the apparatus when the lifting sling is unloaded in said second position of said lifting sling latch member (9). A lifeboat and a method is also described.
A securing device configured for preventing unintended release of load from on-load safety hooks is provided, the securing device at least including: a) A first manually releasable securing member (1) configured for engaging a hook housing through at least one engagement means, b: At least one securing means (72) that makes sure the securing member (1) is maintained in a fixed position relative to a release mechanism (3) and engaged with the release mechanism (3) mounted in the hook housing. According to the present invention, a safety assembly for preventing unintended release of load from on-load safety hooks is also provided.
The present invention discloses an encapsulated lifeboat provided with at least one lifting strake (5, 6, 7, 12) onto its hull where at least half of the length of the one or more lifting strake are arranged above the waterline (16) of the lifeboat, thereby providing a soft movement when partly or fully submersed in water. Moreover the encapsulated life boat is adapted for use as a free falling lifeboat.
The present invention concerns a winch 1 for lowering lifeboats with a redundant breaking system. The winch includes a double winch drum (22) for simultaneous accommodation of two winch wires (23, 24). A primary winch gear (20) is mechanically connected to the winch drum (22). A primary brake pump (2) with an inlet and an outlet is mechanically connected to the primary winch gear (20) through a shaft. An electric motor (15) for driving the winch is located on the side of the winch. A transmission between the electric motor (15) and the primary winch gear (20) connects the motor (15) and the primary winch gear (20). Furthermore the winch includes a normally applied, primary brake (9) connected to the transmission. A primary throttle valve (8) allows a first flow rate f1 through the primary brake pump (2), connected to the outlet of the primary brake pump (2). A tank (4) for a hydraulic fluid is in connection with the inlet of the primary brake pump (2). A base (26) provides a means for attachment of the winch (1) to a foundation. Furthermore, the winch (1) comprises a secondary brake pump (3) with an inlet and an outlet, mechanically connected to a secondary winch gear (21), a normally applied, secondary brake (10) connected to the secondary winch gear (21), and a secondary throttle valve (8) for allowing a second flow rate f2 through said secondary brake pump (3), connected to the outlet of the secondary brake pump (3).
A cruise ship (1) has an escape system, wherein the system comprises a lifeboat (2) and a tubular tunnel structure (4) that extends into the superstructure (6) of the ship (1), the tunnel structure (4) being formed at a fore end (5) with an opening (8) extending through an external side (10) of the ship (1) structure. The escape system also includes a securing and releasing mechanism (not shown) for the lifeboat (2). The securing and releasing mechanism includes means for retaining the lifeboat (2) within the tunnel structure (4) and may be in the form of typical known mechanical attachment assemblies. There is a supporting structure (not shown) for the lifeboat (2) situated inside the tunnel structure (4). The supporting structure may be in the form of known types of launching slide-ways. The lifeboat (2) is a free fall type lifeboat and is stowed within the tunnel (4) in contact with the supporting structure. The tunnel (4) is formed with passage access to the lifeboat (2) from several different deck levels (2a, 12b, 12c, 12d). The passage access may be in the form of access doors located adjacent the lifeboat providing direct access to the lifeboat from several decks (12a, 12b, 12c, 12d) simultaneously. The access may be through doors in the lifeboat (1) canopy directly into horizontal seating decks.
